Many states will be incentivized to keep the compact passes because it means the election stops focusing on a handful of swing states.
Every presidential campaign will have to adopt a 50 state strategy, meaning a lot of states will receive political attention they never get because they aren't swing states.
The legislation has to all-or-nothing precisely because of the effect on political attention. If a state awarded its delegates by national popular vote before the magic 270 was reached then politicians can win that state by maximizing their votes in other states so they would be incentivised to put more focus on the states that aren't signed up if they expect to win the popular vote, reducing the political attention paid to signatories.
When the 270 mark is passed, it has the effect of making every vote equal everywhere.

And here was me thinking they wanted to burn down mosques because they hate muslims! Oh how stupid I was!
Clearly if it wasn't for the price of petrol, rent and Big Macs, these economically anxious upstanding citizens would want to just give every immigrant and every muslim a great big hug!
