It will make web scraping impossible. You will not be able to install any software that can do that because it won't be let in to app stores (i.e. it will never get the right keys and permissions, websites won't even respond to it as it won't have attestation).
If you somehow try to work around and use your "attested" machine and user id to do this (because websites will require it and your script can't have it, but may be it can run under your user account, for example) - monitoring systems will soon block your account for "suspicious activity" and it will be next to impossible to re-instate because Google and Microsoft don't provide any human support, unless you are some 1mm+ influencer on instagram and will manage to start a rukus on social media.

The outlook is quite bleak :-(
