But hey let's now analyze what you are saying...

Which rule? Where on the agreements you accepted as a user of twitter did you agree that your publications will be 140 chars long?

Are normal users of the 280 char limit warned that they posts will be cut or deleted if the feature is rolled back?

Has twitter always had the same length limits showing that 140 chars is a hard design limit?

So, why would not allowed user's tweets pollute the DB and the other users not?

Now, stop looking at your inflated ego and consider that not all exploits cause the same damage.

Because, if you submit a vuln report to a company without being able to explain how they are impacted it will be trashed away.

If all you care about are exploitable you're-pwned bugs and not general "bad idea that will bite you in the ass" you're not very good ;)
