Am I overly cynical, or does this all work out perfectly for some vendors?

Yup, folk purchasing these *should* have known (not like there was no discussions of this), but, well, not everyone spends all day reading NANOG / RIPE / CIDR report...
I am not an operator, but I used to be a *really* active routing engineer once upon a time in the stone age :-) and what really bothers me is the serious lack of general awareness on the issue of routing table size, aggregation, and stability, and what effect it has on the global Internet.
Especially questions like this:
"Is it time to switch to all IPv6 yet?"

If anyone *seriously* believes that IPv6 will have any positive effect on this particular issue, you are sorely misinformed. If anything, it will make the problem worse, since the ability to "get aggregation wrong" will be much easier.
I'm not being cynical, I'm being a realist. :-/

p.s. I recall some IPv6 prefix growth routing projections by Vince Fuller and Tony Li from several years ago which illustrated this, but cannot find a reference at the moment....
I found it: "Scaling issues with ipv6 routing+multihoming" Vince Fuller, Cisco Systems http://iab.org/wp-content/IAB-uploads/2011/03/vaf-iab-raws.pdf I think the slides [above] were done for an IAB routing workshop in ~2006.
