Give me a fucking break!

I have no massive love for Comcast, but are you seriously going to complain about 48.5 kilobytes against your data cap??? This person is desperately seeking something to complain about because they don't like Comcast, not because some harm has been done to them.

It's 50 kilobytes. Your cap is what, a terabyte? That is literally 1/20,000,000th of your data capacity.

It's also impossible to do over a secure connection!! The thing happening is your ISP (the people you give your credit card to) informing you of potentially going over your data cap, by using an insecure connection you are initiating. You already trust them financially, and they're only doing this to help you. They are in no way making you any less secure than you already were. The only "dangerous" thing happening is your use of an unsecured connection!

Oh, I'm sorry, are you a disabled user? Do you work on behalf of disabled users? Have you heard complaints from disabled users about this particular alert breaking the internet for them, because disabled people have never seen a pop-up before?

Yeah, the web sucks if you're disabled. This particular "attack" is no different than just the regular everyday experience on the web. Please write another post just about only this subject, and I would take this seriously. But in truth, you're just piling on anything you can to make this seem worse.

Major loss of personal investment? Are they an ambulance chaser in their spare time and the old, non-secure apt repo they're using delayed them?

Dear User, please get over yourself. Sincerely, The Users With Actually Serious Problems.
