It just amazes me to no end how people can defend a company that removes functionality that was paid for after the fact. In some cases people have paid for the air suspension specifically for the lowering at highway speeds to reduce range. Tesla has pushed the air suspension using that exact reasoning. Removing it like they have done is not acceptable, and frankly unless Elon's blog talks about the partial refund they plan to issue to the people who have paid for the air suspension I really don't see how what he has to say is going to matter.
