The internet has very much moved on.
A three minute, 1080p YouTube music video encoded in AV1 video with Opus audio is 30 megabytes. No one bats an eyelash at downloading that.
To prove it, this one has been downloaded 2.6 billion times: https://www.youtube.com/watch?v=ekr2nIex040
To even further prove it, this one has been downloaded 17 billion times: https://www.youtube.com/watch?v=XqZsoesa55w
Yeah, home internet (cable, etc) is fast. Mobile internet is not.
Seems plenty fast enough to me.
I have an old phone. I'm on one of the cheapest plans. I ran a speed test with https://speedtest.net and I got 124 megabits per second. That's 15 megabytes per second, 900 megabytes per minute, which is 90x more than YouTube's 1080p video rate of 10 megabytes per minute.
Ruffle is also available as a Firefox extension. Maybe install that and be happy: https://addons.mozilla.org/en-US/firefox/addon/ruffle_rs/
