Ask anyone in your professional circle what they think of LinkedIn. The answer will most likely be a sigh, followed by “But what can you do?”

This reaction captures the platform’s central paradox: criticism is growing, but usage keeps rising – because there is no alternative. LinkedIn has become the Facebook of the working world: a place you have to be, even though you don’t want to be there.

But what exactly are the problems? From conversations with professionals and a systematic review of online discussions, four core complaints emerge.

1. Critical voices are being suppressed

Perhaps the most emotional accusation: LinkedIn appears to algorithmically downrank critical comments. Post a nuanced but critical opinion under someone’s post, and you’ll often find your contribution receives far less visibility than agreeable replies.

The result is a culture of “positive toxicity”: everything must sound upbeat. Genuine professional debate – which should be the very core of a business network – is systematically made invisible.

There’s a strong suspicion that paying corporate customers are being shielded from public criticism on the platform. For a network that positions itself as a place for professional exchange, this is devastating.

2. The AI content flood devalues expertise

According to a study by Originality.AI, 54 percent of all long-form posts on LinkedIn are likely AI-generated. Since the launch of ChatGPT, this share has increased by 189 percent.

The pattern is always the same: a dramatic opener, followed by single-sentence paragraphs, topped off with an “Agree?” at the end. Add automated comment tools that paste generic approval under every post.

The real problem: genuine expertise is being devalued. When an experienced engineer writes a technical comment, it gets buried under hundreds of AI-generated comments and becomes indistinguishable. The expert’s voice drowns in the noise.

The platform is optimised for engagement farming, not actual professional networking.

Ironically, LinkedIn’s own algorithm now penalises AI content with 30 percent less reach. Yet the problem keeps growing – because the barrier to publishing an AI-generated post is so low.

3. Data lock-in by design

Try exporting your LinkedIn data. What you get is an archive in formats that no other system can meaningfully process. Your contact network – potentially built up over years – is not portable.

This isn’t an oversight. It’s strategy. The more you invest in LinkedIn, the higher your switching costs become. The network doesn’t belong to you – it belongs to Microsoft.

In an era where the GDPR enshrines the right to data portability, LinkedIn’s practice feels anachronistic. But as long as there’s no alternative to switch to, the right remains theoretical.

4. The Microsoft machine

Since Microsoft’s $26 billion acquisition in 2016, LinkedIn has been increasingly integrated into the Microsoft ecosystem. Outlook, Teams, Copilot – LinkedIn surfaces everywhere.

For Microsoft, LinkedIn is a data treasure: hundreds of millions of professional profiles, relationship graphs, career histories. This data feeds into Microsoft’s AI products.

The question is: is LinkedIn driven by its users’ interests or by its owner’s corporate strategy? The increasing AI integration, the opt-out-rather-than-opt-in policy for data training, and the algorithmic manipulation of the feed all point to the latter.

The paradox: everyone hates it, nobody leaves

Despite all these problems, LinkedIn continues to grow. One billion users worldwide. In Germany, 15 percent of the population uses the platform – and rising.

The reason is simple: there is no alternative. XING, the only European competitor, lost the fight and retreated into being a job board. Decentralised approaches like Mastodon work for social media but not for professional networking.

The real insight: the problem isn’t that LinkedIn is bad. The problem is that LinkedIn is without alternative. And that’s precisely what makes the situation so frustrating – and so interesting for anyone thinking about the future of professional networking.

The question isn’t: how do you build a better LinkedIn? The question is: what would have to happen for people to have a reason to switch?

In Part 2 of this series, we examine why Europe’s only attempt to compete with LinkedIn failed – and what we can learn from it.
