There is something that took me a long time to fully realize about having cats that went a long way to helping me both understand how best to care for them and how to handle the frustrations that caring for them brings. I'm a caretaker for basically wild animals. I'm not their owner. I'm not their parent. They are wild animals that are not really adapted for the environment that humans have put them in, so we as a society need to do what we can to keep them healthy and happy. That means inviting them into our homes and making it as hospitable as reasonably possible.
I've done a lot of research on cat's needs. Healthy diet and mental stimulation are foremost of these. I found healthy food that they like and keep them to a feeding schedule. I play with them actively on a regular basis and give them lots of space/things that they can enjoy on their own as well. All that done, my cats are appreciative of the environment they're provided and the food and occasional treats they get. They are two of the most well behaved and loving cats. One is pretty independent most of the time, but will snuggle in calmer moments. The other is a snuggly goofball who just wants to live in my lap.
Teaching them tricks can also be part of that mental stimulation. It's recommended by cat behavior experts. And part of being a caretaker is keeping them safe, so teaching them "no" and boundaries is important. What helped me with all of this was setting aside specific times for play/trick teaching time (Before feeding is best, as they're more motivated to do things for food if they aren't full). Routine is important for cats. And then an occasional random play session when they're not used to it is a special treat for them.
You clearly care for the little guy and want the best for him. That's great and so important. You'll do great.
I would argue that it's more just a, for once, positive side affect of the bloated prices we experience in everything. When you get a buy one get one free deal with glasses, you can shop around and see that they aren't charging double for the single pair. It's on par with what you pay for a single pair elsewhere. It just means that creating a pair of glasses isn't as expensive as they want you to think.
T-mobile isn't paying full price per Netflix subscription they give along with a cell phone bill. They may even be making money. Netflix subscriptions overall are down. Netflix has been desperate to get more people signed up. It wouldn't surprise me if this is considered a promotion for Netflix. They pay Netflix to lump it in with cell phone plans to get people who previously didn't have their own Netflix account to now be signed up. Once that free year or whatever ends, a percentage of those people will certainly pay for it. That biggest hurdle of signing them up for their own account is done.
