Why not use a desktop/mobile mail client of your choice to access gmail over open protocols? Then they can clown up the web UI all they want and it won't matter to you.
If you are using multiple machines, your desktop client will be a huge headache to set up each. Business computers at work have outlook, but personally, I cannot use the client(s) for my 6+ separate computers. Browser email is the way to go.
OK, but "huge headache" is somewhat exaggerated. For many clients, gmail connection settings are a preset option, where you enter a username and application password. It's a one-time configuration.

My condolences.

You are perhaps an outlier? But I can see how it's a hassle in your particular case.
Outlook type of software download all of the emails. Which means gigabytes per account. I use multiple google emails (gsuite), and this makes things harder.
