And it possibly costs you new business cards, and having to let everyone know that you have a new number, and changing any social profiles, etc.

...or Apple could stop making crappy software like this ;)

Unfortunately Apple has zero incentive to fix this bug. Why should they care about customers they already lost?

I try and be very helpful to customers I'm losing... they might come back one day or recommend someone to me.

So when a new potential customer comes in, they don't have to worry about vendor lock in.

The fucked up thing is that is actually benefits Apple. The economic value of your subscribers it approximately the number of subscribers times the switching cost. This bug raises the switching cost and therefore makes their customers more valuable.

Well, it will at least annoy their tech savvy customers since they know that it's Apple's bug.

One of these options is under your control, one isn't.
