No. They made under $250 million in PC sales revenue last FY...the discussion is about PC, not PC & mobile so no reason to bring mobile into the conversation. And that is revenue; net profits were quite lower if you're taking into account the costs for each port (some being > $30 million), the 30% cut Valve gets from sales on Steam, so on and so forth.
This doesn't have anything to do with the games on PC, and I'd wager the vast majority of the MAU increase was on the console side. So while on one hand it can be said "the PC ports aren't hurting console MAU growth", on the other hand it can equally be said "why doesn't PC contribute much to MAU growth when we're putting all this effort into the ports?".
The new PC fans can't generate even $250 million in revenue (not profit, which would be lower) in a fiscal year and a lot of that < $250 million was from Destiny 2 MTX content.
The only respectable part in this is that, yes, some are buying the console. Which was the original plan under Shawn Layden: to tease PC owners with late ports of some of the GaaS and maybe 1 or so traditional AAA releases preferably within a year or two of the next game coming exclusively to console (this was the case with HZD port, and for GOW 2018 getting ported 2-3 years later planned within 1 year of Ragnarok which got delayed a year, but still fits the 1-2 year window mentioned prior).
Under Jim Ryan that kind of went out the window, between 3-month ports of some games (TLOU Remake), and significantly more of the traditional AAA 1P games being ported to PC within 1-2 years of coming out on console. That has created a cadence for quite a few, who are now assuming that all PS 1P must be coming to PC either Day 1, or within 1-2 years of console release, regardless if there's any new installment planned for console within 1-2 years after that port or not. This can become very damaging long-term for Sony/SIE retaining hardcore/core enthusiasts players predominantly within the PlayStation console ecosystem for the majority of their spending dollar and playtime.
Not to mention, that could also lead to reduced incentive for those types to consider buying a PS5 Pro, or even a PS6, if they have reduced or no FOMO, and can afford to wait it out until the inevitable port 1-2 years after initial release. Don't underestimate how quickly someone can switch up their gaming habits if one platform is giving them so many reasons to go to another platform. Again, we're seeing this decline in real-time with Xbox; I don't understand why some of you vouch for PlayStation to take a similar path, even if the fall would be softened somewhat simply due to Sony's gaming brand being larger.
