Don't you think its time consuming for companies to answer small questions all day long like a seat post size when the local dealer can answer the same question, and since thats where the replacement part is sold? Any LBS can tell the seat post size if the OP brings his in. The OP is just venting, he doesn't tell us any info such as model and year for us to help at all. He is just venting an opinion to disparage a brand because he doesn't agree that all the makers do the same thing. My local dealer will answer any Airborne question I have even though they didn't sell me the bike.

I had a Jamis once that due to an accident, I bent the fork. I got help from a store that didn't sell Jamis, it was a sporting goods store actually. In fact that store even ordered a new Jamis fork for me, installed it and everything.

I guess you won't own a Trek, Colnago, and countless other brands. Many don't have email/contact info online. They feel thats what the dealer network is for. They spend years getting this network up to help you.

For people unsavy with the internet who still demand an email, there is countless sites that generally have the same account setups.

sales@$%^&&.com
support@$%^&&.com
webmaster@$%^&&.com

and so on. You can usually figure out how to email them through trial and error.
