There are copious hosts in the europa.eu domain. Most of them rudely stonewall Tor users without explanation. Ironically, sometimes they are asking for public feedback on a privacy-related policy but then they block Tor users who would have the most insight.

Few examples of EC sites that are exclusive access:

Often an open access host links into commission.europa.eu, so people might be part way through a transaction and cannot proceed.

At least eur-lex.europa.eu is open access. That’s the most important one because it publishes enacted law. Yet commission.europa.eu is quite important so definately an injustice that that site is access restricted.
