That is cope from fanboys imo (not direxting that to you specifically of course).
Microsoft absolutely cares (or at least, cared) about hardware, Phil Spencer's leaked emails to Nadella and Hood (and how much money they spent this gen on HW subsidies) prove this without a shadow of a doubt. He talked about having a plan to win the gen in an email that specifically mentioned his closest console competitor and its price tag. When Redfall flopped critically he came out and specifically cited the Xbox One v PS4 gen as the worst generation to lose.
All actual indications were that they really cared about HW and it was the core of their strategy.
The part they used to not care about a lot is profits and margins, but I sense that this has changed after ABK closed. They found themselves with a lot of software but with no big console installbase or big PC store of their own to sell it on, not to mention losing exorbitant amounts of money on HW and maybe even GP too.
With all the above in mind, the reasons for their pivot to being a mega multi-platform publisher has become quite clear.
