I would give a free non-commercial (or in better words, a non corporate) service this leeway - as a user I haven't paid for it.

But as a paid service - where you've been a paying customer for many months - and a service that is targeted towards corporate customers this should just be a given.

The run around about user data belonging to users and so on is just ridiculous. Yammer helped us to create a corporate network, where the data belongs to the company - so when we want to leave it should be as easy as signing up - hit delete and you're done.

It doesn't matter if their systems retain the data for a few weeks and batch delete it later.

I'm sure that if a larger customer expressed this, they would bend over backwards to accomodate. Just feels like they're screwing the little guy.
