If 1% of your revenue is worth not spending a few hours to figure out BS PCI stuff I suggest you rethink your priorities or you're doing really low volume where 1% is like $5.
This kind of tone is generally looked down on here at HN. I think there's an argument to be made on your side, but you're doing an exceptionally poor job at making it in a civil and friendly way. I'm genuinely interested in the other side of the story, but you have to have the discussion in good faith.
There is a good argument to be made on his side. But it's a business decision on what adds the most value for people.
For most people, they aren't (and don't want to be) experts in payment processing. Improving their product moves the needle by more than 1% for the same (or less) effort than spending time on payment processing.
Stripe is an amazing service and their founders are amazing people. I wish I could blow them, but they probably wouldn't even let me b/c the VCs are already all over that. On the other hand, for people who enjoy saving money, becoming PCI compliant and saving 1% + trans fees is another alternative and there are numerous tutorials available to help anyone do that within a few hours even if you are severely autistic.
No need to be an ass. Also, it's business 101 to focus on your core and outsource the rest: so yes, it absolutely is worth using stripe rather than building payment architecture yourself. You are probably the only person on Hacker News that thinks building all this yourself makes sense.
It's business 100 to not waste money. If 1% is not a lot to save you have a hobby, not a business. I do see you enjoy using every service imaginable. I imagine you are building your dumb idea on top of Amazon SES or sendgrid. And you even used some other dumbass start up to make an email submit form for new startups. You're a pro.
