Doesn't matter ... you'll do better addressing the customers' concern rather than being rude and indifferent by suggesting "then don't pay" which appears to counter your business objective. That doesn't help anyone.
At the very least, the update notices are much too frequent in my opinion. Regardless of the reason, Glassware, while a premium product, is the #1 "nag ware" on my computer. I am certainly not going to pay for that. If you are satisfied with that, then I'll have to consider just removing it ... I got along without it for decades so I can do without it again. I'm sure a competitor will arrive eventually and offer a good product with customer service better than a "take or leave it" attitude.
Or, you can address you customers' concerns in a positive, proactive approach which should help everyone.
So there ... that's my two cents ... "take it or leave it"!
