Not caring about customers is not completely accurate. Not caring about fans rings more true. Up until now, Konami has been on the right track. But all of a sudden they changed their priorities radically. And you're right, they are trying to create a new fanbase. But it's a fanbase built on gaming appetites that will not result in something that will keep its soul for 25 years.
Creating clones of the one succesfull game for more then ten years and two medocre (gameplai-wise) entries in the series is a "right track"?
Cloning is much more damaging tactic for a franchise in the long run than any of the reboots and changes in general that could be. It alienates some fans and makes franchise stagnate. Some fans eventualy evolve into close minded pond that think that "cloning and self-repeating" is the only way for the franchise to exist. And any changes and additions generally meet with heavy criticism and discourage developers to add new things to the formula and eventually leads to further cloning and stagnation of the series.
If they finish the classic timeline properly, the LoS route might create a new, stern direction with the approval of some old fans too. But the way things are now, I know they won't. After they figure they can win some "old fans" over by throwing a bone every now and then in the style of Harmony of Despair, they'll suck that stunt dry until ClassicTimelineVania has served its purpose and RebootVania will go on, walking on sticks. It's a decision that might go as far as damaging Konami's overall reputation.
With IGA-style story telling it was pretty impossible to give any reasonable conclusion to the old series.
And Konami doesn't care about reputation in the eyes of the relatively small group of fans. They care about money.
Cutting corners by trying to replace an established, relatively old series with almost everything changed and thus ignoring what fans of the old style want?
What is an old style of Castlevania you're speaking of?
Claasic'Vania? Metroidvania? 2D? 3D? What?
The series had changed and evolved throughout the years. It didn't had one single style that defined it. And I'm not talking about fan's preferences...
My point is, pissing on fans always turns sour eventually, especially for a series that has/had a relatively small, but tight fan community. Underestimating the motive for consumer loyalty and aiming to please an instantly more lucrative target group not based on a "love" for the original product is a recipe for destroying a franchise.
As much as cloning it from one game indefintely.
And what so horrible to Konami in pissing of small number of fans that doesn't ultimately decide number of sold copies? Castlevania fandom is not that vocal or influental to decide Konami politics. And Konami is not small scale developer that depends on small communities and underground titles popularity in order to survive.
