I would worry about my IP address at home ending up on a blacklist, even with a bridge. Google and Microsoft have hidden blacklists with secret criteria to be listed there, and to get off them once listed is a long-winded pain. You only know there is an issue when emails won't arrive at gmail or Microsoft managed accounts and some web pages won't load.
If anything, Alphabet and Microsoft are among the last ones to make a fuss about running a relay. Whatever I think of both companies, nowadays their security teams are top notch experts. They actions aren’t rooted in hearsay and ignorance. In 10 years, including an early experiment with a limited exit relay, I experienced zero issues.
In my experience the biggest offenders are: • Governmential agencies and companies, with their networks run by absolute ignorants. Hardly capable of using a computer, shielded from the outside influence by procedures, protected from responsibility by operating within a political environment. • Small entities, both commercial and not, which are ignorant or lack resources to remedy the situation. They hear word “Tor,” they think “evil,” they blackhole packets, period. There isn’t even a way to contact them. • Companies offering security-as-a-product, or rather their customers. Customers blindly delegate tasks to the company, usually waiving their agency in that matter. The solution suppliers primarily care about brand image and marketing, not about actual quality. End of story, you’re trapped between “we can do nothing” and “we don’t care.”
