Netscape story? MS because dominant in browsers (for a while) because of the nasty lock-ins, not because of any positive iterating. Their own slowness became their downfall - IE didn't iterate for a long time, and when they realized that competition is way ahead it was too late for them.

MS mentality barely changed. Lock-in remains their primary strategy in many areas (it's well described here: https://en.wikipedia.org/wiki/Criticism_of_Microsoft#Vendor_...).

In today's world though it's only backfiring at them, because they have no domination as in the past.
