I did not know
1) that Roblox was such a big thing (they are apparently bigger than Nintendo now). I thought it was just another random game among thousands.
2) holy shit wtf they should be made illegal by law

I think the first vid in that series had more to say than the second one, which I found to be a bit sensationalist. Besides the title being a little clickbaity (I wouldn't really call what Roblox did "pressuring"), a lot of the problems mentioned here are not exclusive to Roblox, but universal to most platforms. That story about the 11-year old girl being sexually harassed on Discord has a Youtube equivalent with the Pyrocynical scandal. Both are awful, but both scummy perps ultimately got away with it because nobody has figured out how to properly police a platform yet. As a result, that alone doesn't make me angry enough to want to cancel Roblox.
Same with the item market and the third party websites*. Steam has had a virtual market place for years, and its inevitable for 3rd party websites to pop up in any multiplayer game with tradable goods. Team fortress 2 has one. WoW has one. I'm pretty sure Runescape's got one too. Unless you want to ban in-game trading entirely, you can't really blame the companies for it. That's why people aren't usually up in arms about it.
The only things about that video I found poignant were the terrible customer support/fraud prevention (Kids get scammed easily) and the Child corporations. Child corporations are rotten. It's cute when strangers on the internet band together to make a mod or a Yandere-simulator clone, but once real money comes into play, it becomes very unlikely for people to get their fair share.
To your points I want to say:
1) Roblox is definitely more popular among kids than Nintendo (say hello F2P business model), but it doesn't make as much money as you think, in spite of how scummy the business model is. It's only bigger than Nintendo in terms of stock price and market cap, but that's mostly just hype. It only went public a couple of years ago which is why the stock is so
!HOT!2) Definitely. If you're going to offer to pay kids for their work, either go all the way and pay them a fair well-regulated wage or don't bother. This revival of 19th century labour practices should be squashed, just like it was last time. And frankly, it's quite tragic that our youth are being corrupted by the profit motive at such a young age. I remember how greed infested the modding scene became during the brief time paid mods were a thing.
If you haven't yet, you really should watch the
first video. It does a better job of breaking down what modern Roblox actually is, and shows you what a rotten foundation the company is built on.
*Roblox's biggest crime in that regard is obfuscating the real world value of the items through Robux. Kids are likely to literally have no idea what they're spending when they buy an $800 virtual hat.
