Apple has deployed a system called Private Access Tokens that allows web servers to verify if a device is legitimate before granting access. This works by having the browser request a signed token from Apple proving the device is approved. While this currently has limited impact due to Safari’s market share, there are concerns that attestation systems restrict competition, user control, and innovation by only approving certain devices and software. Attestation could lead to approved providers tightening rules over time, blocking modified operating systems and browsers. While proponents argue for holdbacks to limit blocking, business pressures may make that infeasible and Google’s existing attestation does not do holdbacks. Fundamentally, attestation is seen as anti-competitive by potentially blocking competition between browsers and operating systems on the web.
Back to the days of using a different web browser for each website. I remember the acid test, IE 5.5, etc. Not fun as a user or web developer.
if you use Safari or Firefox as your main browser it’s already been this way for a while. websites are only tested against Chrome and often times when something doesn’t work switching browsers temporarily alleviates the issue. it’s a sad state of affairs in browser land.
