Yeah, my first thought as well was that "pulling up" would be pulling the steering wheel back, which wouldn't do anything. Certainly wouldn't swerve the car all the way off the road, you wouldn't want to jerk a plane left or right in that scenario either.
So... definitely made up. But still an amusing greentext.
For sure, valid to fear the enshittification of steam. But they aren't killing proton. Maybe ignoring proton at worst. But Steam has profit motivations for not being reliant on Windows, which has actively been trying to supplant them with the Windows Store for years.
As another separate, profit-motivated company, with a gaming division and a lot to gain from eating Steam's lunch, Microsoft is not Steam's friend. Proton is a critical bargaining tool for them, and not having to include windows licenses for devices like the Steam Deck helps their costs too.
