(Hopefully pressure from the low end tool manufacturers who try and compete on value keeps these kinds of things from happening.)
Looking at the sad state of TVs (where the cheap brands just hop on the bandwagon and make a quick buck), I am not very hopeful. Everyone will be as consumer-hostile as they can get away with if they think they can make a few cents that way.

After having recently read too many military sci-fi novels in short succession[0], I started to think how warring alien species would secure their military hardware against reverse engineering. I came to a similar conclusion - there would likely be a whole field of making every possible bit of a device coupled with every other bit, kind of like homomorphic encryption, but done with atoms and fields instead of bits. Like you said - windings that only work if you PWM the voltage precisely, perhaps according to some algorithm that compensates for those windings being scrambled, softly shorted, and otherwise smeared across half of the device's interior surface. Etc. Impossible to fix, but also impossible to figure out without original schematics.
And yes, the way the market is heading, I suspect we'll start doing this to ourselves to secure sales and protect IP.

Large equipment in industries that can afford it is already activated by employee badge for QC and employee tracking purposes so what you're describing already exists in some settings.
Diabolical. “Scan this QR code to watch an ad and unlock 30 minutes of 3x speed!”
Can't have scabs who aren't several years invested in the system doing work. (i'd /s it but the people who push these things will unironically say stuff like that).
Think bigger. Power tools that phone home describing their use and location, all tied to an individual via credit-card checkout (or face recognition) and/or warranty sign-up.
It's probably best to think of the modern world as being constructed with the substrate of a Las Vegas casino.
This already happens in earth moving equipment.
The design of the tools will become increasingly complicated to tightly couple DRM functionality to prevent the trivial DIY electronics hacks that you describe. (My sci-fi brain is imaging motors with wacky windings that need specially PWM'ed streams of electricity to spin effectively, etc...)
I hate our industry so much.
