You're looking at it in isolation and trying to find a positive for consumers that doesn't really exist for the most part though I'm afraid.
So someone comes off the fence and buys an XB1 for a TR bundle you argue, this is good for them. Then when they get hit with the next unfavourable timed exclusive it's a negative for them right? And that's what the culture of timed exclusivity pretty much guarantees will happen.
Big picture is simple: timed exclusives aren't good for us as consumers and only benefit the businesses themselves. There's really no argument around that. Overall sooner or later you're a victim of a timed exclusive not a beneficiary. Doesn't mean they don't make sense for business and doesn't mean we can't acknowledge that but we shouldn't forget the benefits majorly stop there and mostly there's no benefits and only downsides for consumers as a whole.
And Etta it may be reactionary, as in you're responding to others, but if you do it to the extent you go filling a thread with various replies trying to spin the positive you will always end up looking like an apologist. Better to learn who to respond to and who to ignore: replying to obvious trolls or people who don't want corrected never works and just ends up making you look complicit in spin.
Some people are just uninformed and a clarifying reply goes a long way, others are wilfully ignoring facts and if you want my advice you end up being snared by those folks too often.
You're skipping over neutrality here. Why would it be negative for those who already own an Xbox One? It doesn't bring any positives, sure, but that doesn't mean it brings negatives. For them it's just neutral.
As for the second half of your post, thanks. You're right, I have a lot to learn here, and your advice has been immediately helpful. I think I have had some expectations that I should rethink. I'll try to let the answers pool before I address them, and I will bunch them up so as to decrease the frequency of my posts.
