This guy is kind of disingenuous regarding Destiny 2 at least though.
The XP throttling system is basically a direct copy and paste of similar systems like in WoW that were made to prevent repeating exploits for fast level ups. In fact the creation of that system in older games is the direct result of "rested xp" becoming a thing. It's disingenuous to act like it's a system created specifically to force the purchase of Microtransactions when it's lifted from games that even pre-date predatory systems.
The argument also falls apart when you consider even under the old "Throttled" system the game still gives you 9 free chests a week and leveling up still only took an hour of gameplay. It also falls apart when you look at the items in the boxes and see none are worth spending money on.
Furthermore he claims that Bungie "secretly" doubled the experience needed to level up and were actively trying to hide it. The only reason the community caught wind of it is because (I think it was him may have been another Dev) Luke Smith full on said it was 160k on Twitter and the old system was 80k.
Furthermore the reason the rate was capped is because the old system not only Throttled experience gains but also opened bottlenecks. I.E. In addition to possibly not earning as much experience as before you could also gain more than before.
The old amount of experience was set up to take into account variable experience gains while with a system that didn't throttle or de-bottleneck would be to low a of a number further incentivising people to do certain activities over others as the gains would be clear.
i.e. if you only needed 80k to level up and you got 10k per Public Event, why would you do a 10 minute PVP match for 2k? Without the variable feature in place anymore there wasn't a system in place to bump up PVP (or bump down PE) to be inline with other systems. Furthermore he also completely failed to mention that they are already changing the 160k experience needed for level ups since they realized the new flat exp rates don't mesh well with slower modes like Crucible.

All are points of contention the community has been raising. Furthermore Destiny 2 is a direct result of all of D1's chief complaints.
No story? Check.
PVP problems due to 6v6? Check.
Casual Friendly Mechanics? Check
No Overpowered weapons like gjallahorn? Check
No more grinding? Check
The list goes on but a lot of the reasons D2 is the way that it is falls on the community. A lot of the shit it got were requests on the subreddit for 3 years. It's a prime example of your damned if you do, damned if you don't and why you should never actually do everything your vocal minorities ask for.
I'm only 4 minutes in and I'm unsure if I can even finish the video. I'm always down for pitch forks and listening to a good bit of drama. I'm a fan of Jim Sterling after all, but atleast Jim has the tact to present arguments (in most cases) truthfully and without an angle.
I don't know if this guy is just parroting stuff he saw on /r/games and thus doesn't actually know what he's talking about or is purposefully being disingenuous to drum up views. In either case 4 minutes in and this is a poor example to present this guys work imo
