All these companies have done about as much growing as they can. I remember listening to the radio on my drive to work a year or two ago, and they were talking about how Facebook had done internal research and concluded that they had captured something like 95% of the possible user demographics, meaning that they were unlikely to be able to reach new customers because either you have Facebook and you use it, or you've already heard of it and you don't want it/don't use it anymore.

It was interesting, because Facebook/Meta, like Twitter, Reddit, Discord and Tumblr are all for-profit companies that exist to make money, and yet, the expectation of infinite growth from the market never ceases. There will never be a time when the company has grown "enough". Enter the short-term smash-and-grab strategies. The idea is that they know that their business model has peaked in terms of growth and profit and they now need to extract value from the company before the market catches up to that fact. Social media is inherently unprofitable. Nobody wants to actually pay for it, and they do not produce a product, so eventually once the ad revenue has reached critical mass, the users become the product and are essentially ransomed off. Reddit just tried to pass the buck onto the 3rd party app developers rather than the users, but since the API restrictions affects regular users as much as it does developers, it had the same effect.

Suffice to say, unless you are a member of a social media platform that is a non profit, this is going to keep happening. Even if you land on a site that prides themselves on being excellent stewards of their company and never prioritize profits and growth over stability and customer satisfaction, eventually they will be forced to make a decision - lose a lot of money or lose some customers. The answer, sadly, is all too obvious to them by now.
