Lazy loading is implemented in browsers/HTML so blocking JS won't help prevent tracking/fingerprinting there. There are a lot of other means to collect data without resorting to JS too though. The expectation isn't that you can prevent all your data from being collected, but you can (and should) prevent as much of it as you can, when you can. In the case of lazy loading, disabling it not only prevents that data from being collected but it does so at basically zero cost to you (for all but the slowest or most metered connections) and in fact will likely improve your experience since many people find lazy loading annoying in the first place. > if they don't use user tracking and only collect "basic scroll data" anonymously, honesty, I don't see the problem If people weren't evil there wouldn't be a problem but since there are plenty of people who are, and you can't know which sites are only collecting "basic scrolling data" and not associating that to an IP and/or selling or handing that data over to third parties the only sensible thing to do is prevent anyone from collecting that data. Sorry if that data is useful, I'm sure that it is, but it's also frankly nobody else's business and the fact that web-developers have largely refused to self-regulate and be responsible with our data means that smart users will do everything they can to keep as much of it out of other people's hands as possible. It'd sure be a better internet if we could all blindly trust random websites with our data when it is (on its own) low risk, but we can't so here we are.
