It’s not so much the number of forks that is an issue but rather the number of contentious forks that can cause the network to split in an uncertain state (Who gets the hashpower? Who gets the brand? Who gets the ecosystem support?). As far as I can tell, there is more drama going on in the #Bitcoin community than in the #Monero community and there had been more contentious forks with Bitcoin.

The mechanisms that lead to a network upgrade on Monero and Bitcoin are similar so I’m not sure why one would be more resistant to corruption than the other.
