Best way to handle profiteering scam in our condo?

But it would be blatantly obvious to the co-owners if the management or JPM pull out dozens of proxy votes at the AGM and should give them plenty of reason for a vote of no confidence.

Blatantly obvious indeed, but it wont bother the average co-owner in some buildings because he either doesn't understand what is happening and/or doesn't care. I have seen JPMs, committees and management do things here for which they would be arrested immediately in a civilised country. But here nothing happens at all. And if co-owners complain to the land office (which is the only body to which they can complain) they are either told "that isnt possible, you must have misunderstood" or some envelopes change hands, some documents are altered and they are told "that never happened", or they are asked "fine, but where's your proof?". Corruption on a massive scale.
