The Fediverse is going to end up the same way as any and all rational and necessary inventions. For example,

In Illinois, there is Law (its State Law) that any Public Library refuses to stock pornographic literature in the Children's Section is going to lose funding.

People are coming to the Fedi with no purpose, with no intention to contribute, to improve. The Fedi has no value to them, so they do not care about polluting it, damaging it or even destroying it.

People did not "chose against its use", people simply do not care to invest into it, the same way they did not invest in GNU and Linux, or no longer care to protect the purpose of the Public Library system.

Live long enough, keep paying attention, learn to read between the lines and you will see the same.
