I think there are two sides to this. One one hand I agree with you that this isn't an issue for the "general" public. On the other hand I wouldn't be surprised to see centralized platforms like TikTok getting banned, or perhaps simply unprofitable, within the next decade as legislation slowly grinds its way into limit the impact of these platforms. Because aside from anyone wanting to take more control over their own content, the political and social elites (at least in Europe) are currently very aware and focused on the negative impacts digitalisation has had on our society.

In Denmark we're in the process of banning devices like iPads and smartphones from schools and other institutions. We're also likely going to see an age limit on Social Media like TikTok that's around the same age as buying Alcohol (yes, that's a good combination) and a range of other things. In the wider EU, you have privacy and competition stepping in, both banning and taxing these platforms in ways that might make it hard to operate a profitable platform if you're allowed to have one.

It's still a little too uncertain to say anything concrete, but it's certainly not looking like the explosive growth of centralized "free-to-use" platforms will face the same profitable and non-regulated market the coming 20 years that they did the previous.

Someone is going to be well positioned to take advantage of this as people move on from the previous generation of social media platforms.
