Do you remember them all arguing that the ozone layer depletion was a hoax? Why is it that these anti-scientist keep being listened to?

Wall Street Journal has article today reporting that chlorine content in the stratosphere has declined 11.5% 1993 to 2020. That is probably due to changes in Freon.
Its a good example of success in a global air pollution problem. Even China was convinced to co-operate.
Reportedly, acid rain is not the problem it was 40 years ago either.

Good point. Yes, acid rain comes mostly from burning fuels especially coal containing sulfur. Burning low sulfur coal shipped in from Wyoming is a plus. Or installation of (costly) scrubbers. Progress has been made. And coal fired power plants continue to get more costly to operate.
Yes, progress is being made. (But you still have to lime your lawn to counteract acid rain.)
