Co‑opetition?

Some have used the term "Strategic accommodation".

Interesting you bring this specific Mozilla/Google example up since this is the closet thing to seeing this happen in real time:

"Courts and press have noted that Mozilla relies heavily on Google’s search‑default payments, which keep Firefox viable. Recent antitrust proceedings have wrestled with whether (and how) to restrict these payments: a judge ultimately allowed Google to continue non‑exclusive payments to distribution partners like Mozilla while barring exclusivity and some tying/bundling—an outcome many observers said preserved Mozilla’s “lifeline” without materially threatening Google’s core position. That is textbook co‑opetition coupled with what many would call strategic accommodation."
