There is another saying that goes "all pesticides lead to resistance when overused".
The good news is that when you re-introduce non resistant strains, and remove the pesticide, resistance fades away. Diversity equals control, or at least as much control as you got with the kill 'em all approach. There is prevention - the rational steps one takes to prevent something from happening based on careful consideration of the risks and benefits, and then there is the kind of reckless prevention that places the short term benefit at the top of the list and the rest off the list altogether. And shades in between.
I'm sad to say, spinosad is the kill 'em all approach, just like Bt, and to a much lesser extent, neem.
On the other hand, you can't bring a whole ecosystem inside can you? So you need to draw a line for yourself. What are you willing to do?
I can tell you that inside, the line for me is not in the same place as outside. In both cases, I am thinking in terms of IPM. The variables change, that's all.
