That's the fundamental problem with corporate-owned mediums. It is impossible for them to exist long term without being ruined by commercialization because that corporate owner must make a juicy profit sooner or later or else shut it down.
The only viable long term model is decentralization where nobody owns it, so nobody needs to profit from it and the operating costs are shared.
Email (1970s) and Usenet (early 80s) survive in perpetuity because of this (I know most people have forgotten about Usenet but it's still around). It's important to take these lessons to heart. Reinventing yet another proprietary platform with a single corporate owner just to see it inevitably die off when profits must be squeezed is exhausting and a treadmill we should get off of.
