I have a historic car that ended up banned at Le Mans over rules and caused Lotus to stop competing while at the same Ferrari did not get banned from the same race despite also falling afoul of some different rules. at least according to legend, anyway.
According to Adrian Newey's book it came out in 2015 that Ferrari had a secret deal with the FIA that allowed Ferrari to veto any regulation changes. It also is interesting how cars in the early 90s started to have more advanced electronics like active suspension which Ferrari never got to work and then those things got banned.
There is definitely precedent. In ‘62 Ferrari threatened to pull all their cars from Le Mans over some ruling they disagreed with. Lotus went home and didn’t go back to LM for many, many years.
(Reading the Wikipedia article, looks like they only mention two Lotus 23s going but I think there were more)
