If you have a disc copy of an anime, you are free to share the disc.
With a lot of foreign-from-your-country media it is hard to get an hold of that media without spending a lot via a 3rd-party.
If that media is available in your country, then you are free to share the official ways to consume that media.
Having an unofficial copy of a piece of media that isn’t even available in your country isn’t hurting the company behind it, as you are paying premium to a 3rd-party that already bought those copies of the media and now needs to pocket the extra percentage on it.
Copyright almost never applies to the consumer and is more meant to prevent other companies from reselling unofficial recreations or bundles, but of course that depends on laws of your state.
I’m surprised they didn’t do it sooner.
