In addition to being anti-competitive, excising the feature is reactionary.

1) You have no evidence that spammers are using it.

2) You are throwing out current *legitimate* (paying artists!) uses to guard against the potential of illegitimate uses. Perhaps you've heard of the substantial noninfringing use doctrine and the reasoning that underlies it? The feature is content agnostic and should not be excised simply because it can be used for bad ends.

3) Spam can be detected in other ways such that honest uses of the html launch can be allowed to continue.

Thanks!
