It is foolishness to get this far in development without drawing up some sort of development participation agreement that prevents such licensing body schisms.

Whatever mistakes AOM made, they certainly got that part right at the start, and the proprietary actors like MPEG should have learned from their previous mistakes by now.
The challenge is that MPEG itself doesn't do the patent licensing stuff; just the spec. There are disclosure rules in MPEG to minimize submarine patents. MPEG-LA is an entirely separate group from MPEG, and there is no mechanism to require licensors to use MPEG-LA in any case.

There's definitely a lot of talk about how MPEG could more proactively avoid later patent licensing nightmares, and it's been broadly stated that if VVC fails due to patent licensing issues, it will have been the last codec to use the traditional MPEG standards process. MPEG-5/EVC is an attempt to use a much more AOM like process within MPEG.

AOM was definitely very proactive in avoiding patent issues (at presumably tremendous expense in patent attorney hours). And the good news for AV2 is that more and more patents are expiring every year.
