Saying he’s trying to impose his views on everybody is absurd.
How exactly is he imposing anything?
By voicing his opinions asking politely for people to consider it?
It’s you who are telling others what they should do.
And even that isn’t forcing anyone — just giving your opinion.
I think everyone can do whatever they want and work on projects that do whatever they like, and give whatever opinions they want about what others are doing.
None of that constitutes imposing anything on others.
