Xbox users have to understand this before blaming anyone.
The success of Xbox depends on how MS invests on Xbox. If they want to get all kind of games, MS needs to talk to publishers and developers in order to put their games on Xbox. Use whatever means necessary to get those games on your platform.
You can't grow your system, if you don't aggressively invest on it. Especially in key areas such localization in regions where people don't generally speak English.
They also need to set up marketing department in regions where Xbox is weak, in order to promote their system.
If you can't get any timed exclusive, do gamepass day1 games. Or even make 3rd party partnership in order to make AAA exclusive games like Rise of Ronin from Ninja devs.
The market isn't fair. It won't wait for you in order to get those content on your platform. Consumers won't invest on your system, if you aren't not trying to make the system interesting.
You have to put the effort and put something in the table.
Look at what Sony did with PS3 vs what MS is doing now with XBS. I don't that see PS3 aggressiveness from XBS.
The only one that can save Xbox is MS putting those efforts on Xbox, and not blaming Sony for these tactics.
MS did shitty stuff with other companies in 1990s. They shouldn't go around and blame other companies for the same stuff they used to in the past.
