Hey, all legitimate and good reasons for cancelling. And pools are awesome to have in the summer, no regrets on ours.
I thought it was noteworthy because you had suggested a mid May, and then a June 1st opening very confidently from your source and I believe talked about not cancelling your own trip because of this, and now on May 6th have scrapped going entirely. You spoke about specifics regarding SWGE access, transportation, restaurants, and rides running at reduced capacity. After your source changed to June 1st, you then spoke of a June trip as a back up.
I don't begrudge you for doing whatever the heck you want with your trips and your money. And you don't owe any of us an explanation. I'm posting this to remind people to NOT MAKE DECISIONS BASED ON POSTS HERE. And to be fair you may have posted that yourself, that your information isn't guaranteed. But info from sources tends to get repeated and repeated until it's become seemingly official, and I've seen a few people talk about cancelling based on dates and procedures talked about here. Please wait until official Disney information. Even the reliable information may be changing frequently.
