Other pokemon games: take care of your pokemon, lots of strategy when battling, everything can be strong if used correctly
This game: Trash your weak pokemon, pay, pay, pay and tap/dodge, there are only 30 useful pokemon (Maybe less?)
Umm this is not pokemon in real life but a human torture/frustration simulator

"everything can be strong if used correctly"
Proves you have absolutely no clue of the competitive meta of the handhelds. The single player game is easy to beat because they want to let people complete it with whatever they want but it's a different game when you start fighting other people. The meta probably has more viable pokemon per generation than GO does, but still most pokemon are utterly useless.
That can‘t really be said either. Sure, some Pokemon may seem useless, but you have to see their role in their specific tier. Take Emboar for example. Relatively slow, mediocre bulk due to lowish defense stats and a good amount of HP, and good attacking stats. It would barely stand a chance in OU due to Garchomp and other threats. But in NU, it‘s current tier, it‘s an amazing wallbreaker, and it‘s currently even suspect tested because some people think it‘s too strong for the NU and might get banned to RU (if not already happened). But, if you had the right strategy and support, it could theoreticly even put in some work in OU. So you definitly can‘t say „most“ Pokemon are useless.
To be fair, he never mentioned competitive in his post, he said "strong." In that sense, I agree with that statement, but not n the same way. You can make ANY Pokemon strong through gimmicks and shenanigans, which falls under the description of using them correctly, but in no way does that mean that it is viable in a competitive way. Some Pokemon take an insurmountable amount of effort during a battle in order to make them "strong," which immediately removes the competitive aspect out of them.
Pokemon GO is about GOing outside, have a nice walk, catch a few monsters, hatch an egg. Swing by the neighborhood gym to check if somebody put in a defender you never did battle before. Enjoy the graphics when your Loudred uses Disarming Voice to shred a stupid Dragonite.
Sure, you could play Pokemon GO as a competitive game. But why would you want to?
In the handhelds you do not take care of your pokemon, you take care of six at a time only and you trash pretty much 99% of all pokemon you encounter, not by capturing and transferring them mind you, but by beating the living $hit out of them and leaving them to die in the open fields/seas/rivers/volcanoes/deserts/caves.
Also, yeah, everything CAN BE strong if used correctly, but that does not make all Pokemon viably competitive. To make a shuckle competitive in the handhelds you have to go through a long process of chaining stat-swaps and buffs while you hope that you don't die in the process (plus, good luck with doing that in singles without the help of a support Pokemon in doubles format). Yes, it's technically doable to have a Magikarp sweep a whole team of six, but it doesn't mean it is easy or smart to try to achieve whatever lengthy mechanic is needed in order to make it happen. You would never have a puny Dunsparce face a goddamn Garchomp and hope to win that match.
Not every Chomp runs Outrage. And of course, you need a good RNG roll to survive two EQs, but if you survive the second one, you can just spam Roost, which on the long run should give Dunsparce a bit more HP back than Chomp can deal. And then you should without too much trouble be able to stall the 6 turns it needs for the poison to kill Chomp.
