The "disposable" in "disposable email" implies that you don't intend on keeping the address around. Under that use case, the service disappearing after a year or two doesn't cause any issues, because you don't have anything persistent attached to those emails in the first place. Besides, many (most?) other email services prevent you from recovering an email address (usually because a random address is assigned to you and there's no way to pick/recover a previous address), so you're already discouraged from using them for any persistent services.

The emails are disposable, not the service. This causes issues b/c you're constantly having to find and change providers.

Eh, I don't know if that's really a problem. Query "10 minute mail" in Google gives hundreds of results within a millisecond, so... you do this lookup once in 2 years and you're done? Really don't feel like it's a big deal, at least for me

Lots of websites are wise about disposable email and reject those domains. Query "10 minute mail" and you get a list of blacklisted email domains.

The services that new or don't have much traction aren't blocked yet.

Yes, that's precisely why I'm querying more often than bookmarking sites. They "expire" soon so I kinda have to find replacements. Apple's situation is interesting, I don't think sites can ban Apple's iCloud completely. It may also be an opportunity for Gmail to copy the feature..
