At least webviews don’t (yet, Google be trying) have the ability to request attestation & ban me for not using the stock, bloatware OS every device comes with. Bonus that I get to keep my data inside the browser’s sandbox; it’s the easiest way to be safe with proprietary software.
If only my bank could get the memo & make their website not suck (it legit checks for Netscape Navigator 4 in the source) so I can be at peace with microG+LineageOS in the phone space (all the banks here do it & I already switched once until my bank, slowly but inevitably ‘modernized’ their app).
