This seems like an overreaction that puilnishes you more than Adobe. There are a number of other tools - until fairly recently Capture One offered perpetual licensing, for instance. Giving up RAW to spite Adobe is like being angry at Microsoft Office subscription pricing and saying you'll abandon word processors and just use a typewriter instead.
I don't have spite for Adobe, that seems like a projection on your part. But I can't justify the purchase, and have adapted the way I take photos as part of that.
It's more like finding the subscription for a CAD program too expensive, and swapping to something more primitive instead. If that offends you, I think you gotta have a long hard look in a mirror some time.
The point is that there are many options, at many different price points including free, that don't involve giving up 95% of the data your camera sensor provides and don't lock you into getting the exposure perfectly right the first time or else.
FastRawViewer, DxO, Affinity, Darktable, Capture One. Those are just the ones I personally have installed. There's also RawTherapee, a number of camera OEM-specific tools, and more.
