I miss when websites made it possible to do essential things in my daily life without requiring I install something on my device.

Except there were websites requiring you to install ActiveX and proprietary plugins to do anything meaningful as soon as 1995? Also banks requiring proprietary security modules to access your account, they were pretty ubiquitous in the early 2000s where I lived.

The difference now is that accessing services through the internet is a necessity rather than a luxury. I guess passing laws could fix this, but it's exceptionally hard to get anything done through the barrage of big tech lobbying.
