I didn't say anything about popularity, but no, I don't think Lemmy will become popular at the scale the act envisions. Most people will continue to use corporate services for the foreseeable future.

There's a difference between popular and powerful though, and I hope the courts would be capable of making that distinction. I also see a couple of references to the "market" in the act, which I think should exclude Lemmy as long as it's not-for-profit.
