As usual Mochizuki spreading lies and FUD about Sony. In this case cherrypicking some stuff putting it out of context to make it look worse than the nohingburger he really said, which was this:
An executive with finantials profile logically see devs as someone very passionate, hardworker and creative but that obviously -due to the creative process behind making a game- aren't very good a achieving milestones/development schedules/budgetts, growth or optimizing profitability, so in the business side he sees room for improvement.
Normal stuff from any gaming company: a nothingburger. Devs and executives have different mindset and goals.
Helldivers 2 can be played single player. For this year they also had TLOU2R and will release Rise of the Ronin, Stellar Blade, Until Dawn remade, MLB, Lost Soul Aside, Convallaria, maybe Death Stranding 2 and probably more unannounced stuff or games I forget. The only MP (which may or may not have SP content like Helldivers, I bet it won't) they have for this year is Concord.
Sony also releases 4 to 6 games per year, even more if you count the ports. And also breaks record, they did it several of them this quarter.
Yes
It's a normal budget for AAA games today. Games like GTA6, Fortnite, Halo Infinite, Starfield, Diablo IV, Baldur's Gate 3 must have had a pretty much bigger budget looking at the amount of people involved there + years of development.
