In addition, they are pretty useless in some regions where they do not support locally dominant payment methods.
"Personal computer technical support", for instance, is almost certainly referencing the scam where someone cold calls you and tries to explain that your computer is infected. There aren't a lot of legitimate businesses that could be called "personal computer technical support", and I suspect of the ones you may even be thinking of that Stripe may classify them differently. I imagine the mom & pop shops are classified as hardware vendors who happen to also offer services and the more serious versions of that business are "consulting". (And at that point, probably not using Stripe anyhow.)
That's easy to say right? Oh it's a scam.
I can't use Stripe because my business falls into the "Scam" area. Am I a scammer? No because otherwise my business would have failed years ago.
I happily use another competitor. I haven't had any issues with them and since I am not a scammer, I don't foresee any either!
Remember. One mans ITS A SCAM, HE'S A SCAMMER is another mans very successful business which people don't have a problem with.
You may not be a scammer, but that's a horrible argument. Bernie Madoff's scam started in the 1970s. He wasn't caught until 2008.
