I don't see the fallacy in it. It's just pointing out that a little time wasting at scale actually has a big impact.
135 out of 1B isn't big at all, it just looks big because of the biases we have when interpreting big numbers. Not mentioning the fact that the aggregation isn't very relevant (it's not like 135 people will have their entire life wasted while the others are not annoyed at all).
They're wasting 135 people's entire lives worth of time. Every single day. :(
