I know people who lived without Facebook for years who created an account just to get info from their kids’ sports clubs. A lot of them only post data about events and stuff on the Facebook page. No newsletters or anything. Just Facebook.
They don’t really have a choice. You don’t want to ask other parents all the time and they won’t send you an email specifically because you won’t create a profile.
I fully agree with your statement. But in the case above the only alternative is to either annoy other parents every week, not send your kids to scouts camp with all their friends, or just create the profile and only look at those pages.
A lot of clubs removed their website in favour of a private Facebook page. It’s unfortunate, but a reality. :(
