Your second point makes no sense, bcrypt factors are manually increased and require a new write for every item in the store. If we time capsule the SHA1 hashed db of passwords and the Bcrypt db for 10 years you cannot prove that the SHA1 database will be more easily compromised than the Bcrypt database. There may be a cryptographic break in blowfish in the time.

They don't mention a work factor for their SHA1 hash storage, they could be using PBKDF2 for all we know.

If you're looking for something to pick on about Linode here, go after something else, this isn't the worst thing to come out today.
