If you're standing by an abortion clinic, and you're a prominent anti-abortion campaigner, who has been known to harass people in the past, it was considered that your presence there is, in and of itself, intimidating to people who wish to access a legal service without undue interference. The ruling is not intended to prevent any of the things you mention, there are still plenty of ways that organisations can make those things generally known if they wish to, just not a particular group of people directly outside a clinic where they have a history of illegal behaviour.

In terms of misgendering Linehan, singular they has been around since the 14th century at the latest, and many style guides are more than happy with the usage for an individual where either gender is unknown, or where gender is considered irrelevant to the case in point. In this case, I would say the latter applies, but I am happy to acknowledge that Linehan identifies as "he" - significantly happier than he is to afford others similar courtesy.
