Had been using Arc for some time with several qualms about the UX and after trying Dia and finding it's just yet another Chrome, decided to see what Zen is like. I expected the same - but it wasn't. All qualms were solved and I had no rendering problems.
It was only when I noticed the Mozilla login flow I realized I had switched to Firefox - I had an assumption that all alternative browsers are on Chromium now. Really lucky since if I knew, I may not have given a fair chance given the rendering problems I remember from giving it a try 3-4 years ago.
I wonder what it's like in various countries. I was surprised that Japan came up with that, TVer which basically all broadcast shows end up on for at least one week, shown with ads. AFAIK it's driven by a coalition of broadcasters with nothing to do with the big platforms - where there's a will there's a way I guess.
It's always good to have that paper trail for if it indeed does end up as a real dispute. Not car rental but a similar experience with eBay where a scammer shipped an item to an address in my city but not mine, apparently a common technique. I had DHL's email confirming this, and if thinking I doctored it it isn't a difficult call to DHL to verify, but all claims to both ebay and Paypal were denied despite definite proof. More than half a year later I finally got the charge back presumably thanks to having the paper trail for the credit card company.
Naturally I closed both accounts after this experience (the whole point of PayPal was to have protection in these cases...) but I suspect almost all companies are optimized for reducing support costs even if it means just a few lost customers.
