I completely understand why some people may be concerned about this, but most of it is just overblown hype to get youtube views. Yes you will need a cell phone to attend blizzcon. Lets be serious here for a moment, just about everyone and their 2 year old kids now have cell phones. If you are dropping $230 a person on an entrance fee for a con, it is very unlikely you do not have a phone.
In regard to the actual app and spyware. Do a google search for Spyware and AXS and tell me what you you see. I will save you a few minutes, you will see pages of results about blizzcon outrage and nothing else. Someone decided to call it spyware when this data was released and everyone else just ran with it.
I am all for people voicing frustrations when they are unhappy with something, however things have simply gotten out of hand. Blizzard is just one example of many. Anything the gaming industry does is wrong and causes outrage to the masses. It really doesn’t matter what they do, there will be protesting and mass outrage across the internet. The only suggestion I can make is to step back and really look at what is happening.
For example, the youtuber linked here. He has made an entire career out of outrage. He started as just another streamer until his channel virtually died when he quit playing wow. He realized as so many others that the best way to get views is to be as negative as possible. So he started new videos attacking anything and everything. His popularity went through the roof and he hasn’t looked back since. It is in his businesses financial best interest to feed as much negativity into the gaming sphere as absolutely possible.
