Users love big tech. They pretend not to, but they love their shackles.
For instance, when Twitter was bought by Elon and people had that big migration wave... Mastodon was right there, a fully matured ecosystem, same or even better features... yet the majority picked Bluesky, the "features" Bluesky offered are there in Mastodon, the only difference is Bluesky is also owned by private tech bros.
