Agreed. It's Disney that was at fault for having the test go live to the public for that short time. It's not guests' responsibility to assume what they're seeing with their own eyes on the app is erroneous information, or to spend vacation time checking out disboards to see if there's supposed to be a rollout of FP+ or not.
I think the OP was wise, though, to go to guest services and make sure that those FP+'s were valid, only to find out they were not.
But I think the IT CM did well to give the OP traditional FPs to make up for that time spent in guest services and to alleviate any possible dashed expectations, which I think would have been valid on the OP's part, though the OP showed no indication of it.
Even though it was a faux pas by Disney to allow the testing to go live and public like that for a short time, it's still interesting to read this glimpse into what FP+ may well look like, once bugs are fixed. Just because Disney's IT staff has shown incompetence at times does not mean FP+ won't eventually work well (though some may not like the idea that much). They've had IT issues for a long time, but I think the traditional FP system has worked well, and it was groundbreaking stuff when it first came out.
I really don't understand why anyone needs to question the motive of the OP.
OP did not indicate any undue expectations of having those FP+'s honored after it was revealed the public test was a mistake, nor did OP indicate any expectations of any kind of traditional FP remuneration for the trouble. OP only indicated that it was given. I have no way of knowing the OP's motives or actions while actually there; I can only read the OP's post, and in no way did that post read as expecting something that wasn't due.
