I think saying "this is good for Tesla since they're maximizing profits" is considering Tesla in a vacuum.
First off, it ignores opportunity cost. I'm willing to bet that consumer "stickiness" is largely correlated with preferred configuration cost e.g. customers who wanted the base model are more likely to leave if they get impatient or don't get to fully utilize the tax credit. And yes, there are plenty of frugal wealthy people who can fully utilize the tax credit but want a cheap model. As an analogy, think of this in terms of politics: The parties don't have to worry about the die-hards, they'll always show up and vote. They have to worry about the margins and unenthusiastic voters.
Second, while you can make good arguments that the Bolt/Leaf/etc all are worse than the equivalent base Model 3, are they worse when you're discounted (up to) $7500 from the Model 3? Personally I think that Tesla has entry model competition; I would argue that it does not (currently) have well-configured Model 3 competition (they will with the Mission E and Polestar 1 in future years).
I know many of you will retort that there's unlimited demand for $35k Model 3, but I think that's quite a claim to back up in the market as it's evolving, especially from my biased perspective as a happy Volt owner.
