It's about roles, responsibilities and scope as well as the allocation of public funds, which is something that concerns everyone and is a non-partisan issue. We created a public education system in order to educate our children, presumably in order to prepare them for adult life. I'm being intentionally broad about that, as some people would even limit that to "prepare for employment", but I know there are a wide variety of views and opinions on that subject.

Filing lawsuits that target the private sector which are providing services that have little to nothing to do with education and pertain primarily to the private lives of students and families is very outside of that scope (in my opinion). I thought that this was quite implicit in "this isn't what we want our tax dollars funding" but apparently people get lazer-focused on personal wealth?
