True, but the issue is that getting 1M+ installs isn't under the control of the developer. Sometimes things go viral - look at Flappy Bird. Under this law, that guy (if he were in the US) could be looking at decades in prison unless he took enough investment money to comply.
This law also uses a very broad definition of "personal information" that could possibly include IP addresses. So it does have an effect on the entire community, in the sense that every startup hopes to surpass 1M users, and this law will punish them for it.
I don't think it will pass as is, but if it does, this is truly a "sky is falling" moment for US startups. Because it effectively limits non-VC backed startups to less than 1M users, it also makes sure that there will never be a competitor to Facebook or Google. Like GDPR, it locks in entrenched competitors.
