I was specifically referring to their non-enterprise customers. For them, their statement says that "a fraction of our consumer base–home users" [is affected].

Enterprise customers are in a different league: even if individual users are extremely unhappy, it's the IT department who makes the final decision about switching vendors.

I'm extremely unhappy about using Lotus Notes for email/calendar where I work, but can do nothing about it, other than whining on the internet.
