One of the things that frustrates me about apps/web is that most people have no idea what individual apps/sites are “costing” them. Without additional tools and watching Cellular Data settings like a hawk, stupid things can slurp up your data plan. Entire books could be sent to people in a sane format but a 3-line web page wrapped in garbage takes dozens of megabytes? An app that does “very little” is consuming 100 M…
And it's not like people don't have FOSS tools to optimize images, or read for free on how to make browser load smaller or different format (like webp) of images on smaller screen devices.
Often times developers just don't care because it doesn't cost them anything.
So disabling all images in the browser is a must if one doesn't want to pay for grabage stock photos, and experience suffers on all websites as a result. I don't really consider sending all browsing data to Google by using their image optimization proxy as an alternative.
