From what I've read, legally the release of the SRD— a document which contains the rules in plain language, including charts, monster stats, magic spells, etc.— under the Creative Commons license is irrevocable. (Of course, under actual copyright law this is like announcing that public domain game mechanics and processes do not belong you, but that may not really be relevant at this point.) So, according to law, they won't be able to stop that.
Also, there was already considerable commentary among intellectual property attorneys that the original OGL could not be terminated or altered by WotC anyway— that it was a contract which could not be changed, revoked or broken by WotC, no matter what they had just tried to say.
Plus, there was growing buzz about letting the whole thing go to court, where the precedents do not actually favor WotC's position at all.
And they were already out millions of dollars in just one month from the loss of D&D Beyond subscriptions.
Finally, the stock just dropped significantly on rumors of a bad quarterly report.
I don't think they're gonna "lie low and be back."
I expect that at least one executive's head is gonna roll. (There are already rumors that the current guy in charge of all this is greatly disliked by employees and has a lot of negative baggage, making it possible he could be dismissed for "other" reasons as a fall guy to appease customers, employees and angry shareholders… but that's rumor, so I'm not naming him, and execs tend to protect their own…)
