Possibly, but people were worried about this with cloud hosting when it first came out, and it turned out to be a total nonissue.
they are literally going after "creating everything app" and "everything business" (macrohard).
they are litearlly ingesting and integrating your app/business into theirs.
Yeah, I'm not sure the level of trust extended to a company like Amazon or Google will also be extended to one run by Elon Musk, who is notorious for not respecting terms like this.
Not the same thing. Cloud hosting couldn't get away with stealing your stuff. They would lose all trust, which was far more valuable than any individual piece of content.
But AI is literally all about stealing and reselling content under the protection of "AI did it" and "whoopie, we'll take a slap on the wrist". It's reasonable to assume all of the frontier companies are doing this to the maximum extent they can get away with.
