Only when it doesn't cost them anything. When their money is on the line, vast majority of those "concerned" still buy cheaper stuff from overseas. So it's a typical hypocrisy "do as I say, not as I do" :--

Everyone was too stupid to calculate the dollars spent/saved and too impatient to grow the ability. You end up with an overpriced product that has shit reliability. Congratulations.

There is no way you can build in house a generic 25W flyback for 1/10th the cost of an off the shelf design.

Efficiency dropped and the diode ran really hot.

So you go burned by one shitty supplier and didn't try anyone else?

Now, There's a Hobby for Faringdon to take up!

(Fighting windmills.)
Psi:
Engineer: Builds a pretty generic switchmode PSU using values from Excel guide on manufactures website.

Boss: We must protect the IP of this design at all cost!!

Engineer: Rolls eyes.  ::)
Faringdon:
Thanks,
I think especially with zoom/teams this loan scheme could be workable.
