Initially Unity did state the new Runtime Fees were going to be applied retroactively to all games that came out before the policy change, now that's up in the air because of the backlash. If your concern is whether or not Unity will completely ditch the policy itself, I have no idea if it is definite. I believe they're still going to try to go through with the Runtime Fee policy given the current leadership of Unity Technologies, John Riccitiello, or try to do it another way. Take caution with trying to use Unity long term now.

This is Unity's page on the new policy, I wouldn't doubt there will be a sneaky change in the future. Just be on the lookout for any new updates from other sites.

This is the thread about the policy on Unity's own site.

It seems the game is no longer available for purchase but if you already purchased it prior then you can still download the game. I have no idea why it was made like that.

Ah, I see it now the version on the file on Mega says 55, 5.5, the date on itch for some reason still says October 10, 2019. Probably because the file on Mega was the only thing that was modified.

I'm guessing this is for people who bought the game, but I don't see the new build you say you had uploaded to itch. It's still the old build from 3 years ago.
