Maybe, but Apple did not buy Sherlock.

Most companies (the majority, I'd wager) who were Sherlocked were _not_ bought by Apple. Most companies basically got a "sucks to be you", that they found out along with everyone else at an Apple launch event where Apple had, sometimes shamelessly and brazenly, cloned their product. Sometimes, to add insult to injury, Apple would then remove that company's product from App Stores as "duplicating OS functionality".

Allegedly Apple's strategy is often to make an offer to buy the company and acquihire some devs who understand the problem and have experience solving it, and if the answer is a no they implement the feature themselves. I have no idea if that's actually true, or if it happens a lot, but it could be the case that being "sherlocked" is what happens if you turn down an offer. If true, that would make being "sherlocked" irrelevant if the plan is to exit by being bought by Apple.
