After switching over to having a Tor client set up as my system-wide socks proxy, while on a campaign to wean myself off the use of centralised services, I have observed a general trend in accessibility which helps to reinforce this effort.
There is a lot of websites that straight up block you and give you a "permission denied" page. Many other sites that use Cloudflare the cloudflare check page pops up for sometimes as long as 10 seconds.
It seems to me that the more hostile a service is to accessing it via Tor, the less likely it is to respect your privacy.
So if you are trying to cut down on your use of centralised services, installing Tor as a system wide Socks proxy is a good strategy to helping you recognise the ones that should be prioritised for shunning.
