Generally disagree. If you want the Fediverse to become a large open standard, if not the largest, then this is going to just be a matter of course. Companies will seek to commodify all their offerings, whether they use open standards or not. Many exist that commodify on top of open-source software and open standards. The important part is to ACHEIVE the open standard to begin with, and I think it’s short-sighted to pre-emptively block something that could be a strong item down that path, and before it might show itself to be more harmful towards that goal.
It can always be blocked later, situation-depending.
