That is not what I wrote. The phrases "without informing them", "in an underhanded and undisclosed way" and "secretly changing things" were important. I'm all for product evolution, but users should be informed when the product is changed, especially when the change can be for the worse (like dumbing down the model).

I've spent my entire working career dealing with companies that do the opposite. The product still goes stale. Find a better excuse.

You're acquiring users as a recurring revenue source. Consider stability and transparency of implementation details cost of doing business, or hemorrhage users as a result.
