Just like arc web browser i think this is the worst business model
Warp is just something that will, quite honestly, never appeal to me. I don't think the UI is bad, I don't think their featureset is bad, but I also have no desire to use a proprietary terminal app. Tilix is open source and has worked fine for the past 10 years - I'm not giving it up for a chic frosted-glass background and some syntactic eye-candy for bash.
My fear of paid software mostly stems from not actually owning what I pay for. I know people who are (horrifyingly) unable to use Git without a paid GUI that handles everything for them. If one day they update their computer and it's unsupported, or if the developer quits updating it, they've gotta learn a new UI. I'd rather just learn how to use the original tool quickly, and save myself a few hundred hours with 2 or 3 macros.
To each their own. I've paid for too much software that has gone to shit in the past, and I'm perfectly productive with free tools I can actually own.
