That's just bad management. It didn't take them until the release date to realize that SF was the right choice. They just procrastinated until they couldn't anymore when you released your project. I had the same thing happen at a previous job. My team built and executed and hit every object and was ready to ship and that's when they decided to inform us that they don't want to ship what we built and wants us to integrate our features into a product they had acquired. Like that decision could have been made 6 months or even a year earlier. Instead they procrastinated until the last moment. I decided to leave the company after that. Seeing 2 years of effort and good execution flushed down the toilet was very disheartening.
