Why are people saying that Lemmy is free of corporate interest?
Can’t a corporation just enter the space whenever they want to? Can’t they start or even buy out larger instances? Even if Lemmy does take off, wouldn’t this inevitably happen anyway if the space gets popular enough?
So far I think this is the most succinct and correct answer.
In another thread I posted the hypothetical example of a company standing up an instance with a really robust infrastructure (lots of storage, fast and redundant servers, etc). They could use their more significant money and resources to offer things other instances can't. For example they could attract big names to do AMAs, or they could create communities with huge amounts of useful content that lots of people feel is invaluable. People would be encouraged to make lots of communities there and lots might make it their home instance.
Then, once it's really entrenched, the company could decide to start charging a subscription for access, or could start serving up ads. It could be painful to walk away from it in a similar way people have felt pain moving away from Reddit. The difference is that, regardless of how big it is, it's still just one instance among many. You wouldn't have to walk away from Lemmy, just that instance.
