Hate to be a party pooper but the API usage in that log looks completely normal for a PWA… You should be looking at the outgoing network data instead IMO
Maybe one of the devs could advise better if you provide the frontend/client you’re using, and what page you are experiencing the issue on, as well as other instances where it isn’t happening

It happens on 1st page load, then PWA create a lot of cached data.
It doesn’t happen on other lemmy instances, maybe some, but you can check for example lemmy.ml.
You can check using JShelter Firefox addon. So basically application calls a lot of JS API calls to identify system capabilities even if they are not required by PWA. Results of such calls could be used to fingerprint your browser.
Maybe it is some JS library that checks capabilities to load polyfills?
