It's not that black and white. But good job excusing predatory business practices, I guess. lolNot comparable with FOMO. Even so, there are gambling restrictions and licensing needed to operate such, and once they have the licenses, the companies will all run their business on the fact that they are permitted to sell you the thrill and excitement of a winning chance, meanwhile, in some countries, there would be posters saying "Beware of the dangers of gambling" while some waiter is eagerly leading you to the next table with a drink.
FOMO is NOT in the same category as Ludomania, but both are a personal problem which people need to seek counseling in an attempt to manage it. Just because the problem exists within some people does not mean that all companies in the world must adhere to these personal mental issues. Do you claim FOMO because you didn't get to watch a TV show when it was out? Do you claim FOMO for now having a phone model when it was new? Do you claim FOMO when not being able to get all features in one choice, when multiple choices are needed for all features? If you say yes to any of this, and you do have a FOMO problem - then Blizzard is not the only company on your hate list, but EVERY DAMN BUSINESS WHO HAS HAD A SERVICE, ITEM, PRODUCT, EXPERIENCE that can expire or be limited.
If you bring FOMO into a complaint about a company releasing products and updating products, then you are bringing yourself into a deep void of personal mental unrest, and you need to seek professional guidance before it takes you out.
