I think you’re forgetting the power of consumers. At work you might not be able to replace Photoshop or Microsoft but at home you certainly can. The more people that become familiar with alternative software the more likely professionally environments are to adopt it.

Why would a company want to pay Adobe or Microsoft if their employees are more adept with free alternatives? Especially if those alternatives gain feature parity with the paid services while the paid services lock parts behind paywalls and subscriptions.

Don’t let perfect get in the way of good!
