Konami isn't a very dev friendly environment, and that goes since the nineties.
For reference, the reason why they shut down Hudson was also another "power struggle" where some Konami exec was angry with the creator of Momotarou Dentetsu (a popular board game that consistently generates 500k~ sales every year even after 20 years) so as a "Fuck You" they just killed the entire Hudson company.
Arcade and NES platformer devs at Konami were treated like shit, so a lot of them went and created Treasure.
Same goes for their shump guys.
Their SNES-era platformer devs (Sparkster, Goemon, Castlevania, Madara RPG), like Ebisu-san's team, who then went and made Good Feel, now working with Nintendo.
Then Team Silent.
And Suikoden and Igarashi (Castlevania), who lasted a while longer relegated to the humiliation of making abysmal mobile junk (even below licensed anime stuff, where you can still see some of the passion), then got fed up and just resigned to start preparing for going independent.
This week, it was the remaining Tokimeki Memorial/Love Plus guys.
It got worse lately. Even though Konami's overall business is healthy right now (with the casino stuff) their game dev division is the one still generating the bulk of the profit (and even their only casino machines succeeding are ones with videogame branding) and the last few years, as a result of them lowering game development drastically, their video game sales are seeing a really steep sharp decline, and their recent mobile/arcade endeavors aren't doing good.
It's gratifying to see their PR scrambling to release terrified press releases ensuring investors that development on Love Plus and MGS will continue, after treating their devs like shit. Their situation is very different than Capcom - which, while also bleeding lots of talent (Gotcha Force dev, Resident Evil dev (Mikami), Tomba dev, IntiCreate (they still work with them though), Platinium/Clover, and if that even counts Inafune..), they at least weren't complete assholes mistreating all talent or killing IPs left and right without backup plans (compare Capcom cancelling MML3 and reusing its assets for Gaist Crush and EX.Troopers, while Konami cancels games/series as a net loss).
