Edited to clarify.
Things to consider: How much of your data would you be comfortable letting Lemmy sell vs Reddit? If Zuck treated users better, would you be more accepting of Meta monetizing your data every way possible? When it comes to using something for free (tangible or intangible) do you accept a company selling your personal information if their practices align with what you feel is fair?
As ideal as that sounds, who would maintain the noncorporate internet? The government paid for with taxes? The users? How much of your time, energy, money, system would you be willing to sacrifice for a digital public square?
I’d gladly post a git and self host. Just make all ISP’s provide a static IP, VPS, and symmetrical internet like they should be doing already. Also reinstate net neutrality and stop corporate privateer ad stalkers.
