Neither side can be 100% right in this fight....
BUT, the band really seems to be a bunch of petty cunts. Sure, Scott has been battling drugs forever now, but it's not like others in the band haven't had their share of problems too, especially Dean. So, it's a bit hypocritical for them to be throwing this at Scott while they try to fuck him over.
Without Scott they likely wouldn't have become as successful as they are, let alone lived the lives they had.... So to turn around and fire him, sue him, then piss away STP's legacy just for the sake of a potential payday with Chester is about as low as it gets (especially for a bunch of guys with happy families, who aren't on drugs, or hurting for money).
