System updates have been a mostly solved problem since Windows XP (or maybe earlier) and I don't recall updates outright deleting installed software until Windows 10 came out.
Windows 10 obviously uses a different update model (it's essentially a full OS reinstall) but this model should've been developed taking into account the requirements of the old one, and I think "leave installed software/drivers alone" is a very important one.
Releasing a half-baked implementation that is worse than the old one is very sloppy. To the eyes of the user it doesn't matter how "good" the underlying details is (I guess the new model does have some advantages on a technical level), if it wipes out existing software and makes certain peripherals not work it's an overall negative and shouldn't have been released.
