There are multiple comments that meet the exact definition of sabotage. If this:

"You might not like my answer, but I will do everything I can do to stop this."

is not intent to sabotage (even if it might not be successful as Linus could pull in the patch anyway), then what possibly could be?

Pointing out the ridiculousness of comments like this and suggesting the R4L folks push forward while ignoring them doesn't scream toxicity. Refusing to compromise with the R4L devs and calling the additions a 'cancer' has expectedly caused a stir.

I think you need to look up "sabotage" in the dictionary.

sabotage /ˈsabətɑː(d)ʒ/ verb

1. deliberately destroy, damage, or *obstruct* (something), especially for political or military advantage.

2. to intentionally prevent the success of a plan or action.

Definitions from Oxford, Collins, and Cambridge all fit the bill. Even dictionary.com has "any undermining of a cause."
