Forcing updates on home users is unethical at a minimum but very few home users have a true mission critical application that must always be available. Thus, a lot of grousing and aggravation and noise but suits are not very likely. However, most businesses have mission critical applications that can not go down. If the application does not run on W10 this could cost the company some serious coin. Larger ones have the money to sue for damages including asking for punitive damages and some are likely to sue. Migrating from these legacy applications is not a trivial undertaking and an unplanned migration could be a disaster.
