That's because it's Apple. It time to start moving to AMD systems with shared memory. My Zen 3 APU system has 64GB these days and its a mini ITX board.
But before that happened Webtop was amazing! I had Obsidian setup so I could have access on any computer. It felt great having "my" computer anywhere I went. The only reason I don't have it set up is because I made the mistake of closing my free teir oracle cloud thinking I could spin up a fresh new instance and since then I haven't been able to get the free teir again.
I find that a lot of people who say they turn their camera off say they do it because they don't like watching themselves on screen, and don't realise this is optional. Personally I think all the video call systems should turn it off by default, I've never understood what purpose seeing yourself all the time is supposed to have. It would be like having a meeting room full of mirrors.
For my area all the mobile network home internet options offer plenty of speed, but the bandwidth limitations are a dealbreaker.
Everyone I know still uses their cable/FTTH as their main internet, and mobile network as a hotspot if their main ISP goes down.
