Unfortunately, I'm a quite negatively inclined person, so whining, grumbling and complaining are my common activities as well. To not sink other pages, if I want to talk negatively about something (or if I just don't like a paragraph), I will do it here (but still I limit myself).
Gaming
I used to play competitive online games before, but thankfully I abandoned them in ~2021: it's so stupid that those games give you more (often only) negative experience than something positive. No matter if it's team vs team or 1v1 people mostly hate each other simply because someone doesn't play the game as someone else want them to welcome to the internet. It can be perceived as a normal thing (personally I was okay with it when I played online games even if I knew it's wrong), but when you quit online for a year or two, you realize how ridiculous the situation is.
I still have a bad habit though: instead of playing modern games I prefer to read news or discussions about them. Those useless dramas about game development/technologies/graphics/GPUs are more interesting than the games themselves since ! funny enough ! business that exists only to make money treats games as a money making machine. Remembering today's state of probably any large area (putting sugar and wheat into any food to make you buy it even if it's bad for your health; forcing to buy pills to dull the symptoms at the cost of making something else worse; so on), no wonder AAA games crumble in terms of quality and variety 
Subjective and contradictory judgement, to each his own I guess, and yet they also want to add ad banners even to paid games. Public companies chase the value of their stock values to please black 🧱 and other investors, then blaming everything else to justify why another "product to consume" sellings have fallen. However, personally I don't advise to be interested in exploring that nonsense internet noise: let yourself enjoy games you can enjoy, if you can't, switch to something else.
Music
Only one thing makes me sad in music: when people complain about new albums or just new music from specific artists: "it used to be better before". An instance of absurd situation on the example of Infected Mushroom: when I checked comments about 2020+ albums I saw "prior to 2017 was better", when I checked comments about 2015 albums I saw "prior to 2012 was better", when I checked comments about 2009 album I saw "prior to 2007 was better", when I checked wikipedia page about 2007 album I saw "the reviewer set low rating and concluded that blending of genres had not succeeded". Can people just let it go and allow artists create new music they want to create? There is a ton of new music to discover each day! Even I'm not bounded to currently favourite artists, if someone stops doing music in some certain style that I enjoy, I just listen to something else or come back when I get use to the new style if I really care. I think usually music preferences change over time not only among producers, but also among listeners, so do people really think they are able to listen to the same one style without changes for decades?
