Here’s a thought. Send the strata manager the email you want to send the other owners. If it’s saying “let’s change strata managers” and they don’t send it out, then it’s a conflict of interest (morally if not legally).
If it’s “let’s elect a new committee”, as long as you don’t make your reasons personal, they have no reason not to send it out and you have blown their grubby allegations out of the water.
Just a simple email saying : “I think we should do such and such, please contact me.” That would give you the moral high ground.
