Hm, I was already aware things were server specific, so I guess I never noticed it actually said "account wide" anywheres.
I think it's unlikely anyone from Zos will explain the reason (it's been asked about a lot) although a tidbit about it (not why though) is in the support section. https://help.elderscrollsonline.com/app/answers/detail/a_id/31139
If you really do feel that it isn't as advertised you can contact support and ask for a refund. Normally they don't give refunds but it's been seen before that if you honestly felt misdirected in the purchase - they have given them. (they might not, seems to be case-by-case basis)
Greetings,
Thank you for contacting The Elder Scrolls Online team. I understand you have some questions regarding your mount. Below are some basic information to get you on your horse and galloping around Tamriel right away.
• To mount a horse (or panther, or guar, etc.), you must first have one set as your "active mount". This is done from the Collections tab on the player's menu. You can return to this menu at any time to change which mount is active on your character. You will need to set your active mount on each individual character.
• Mounts are account wide, meaning each mount you purchase is available for all of your characters to use!
So, I purchased the Assistants, mounts, costumes and bank extenders. I play on both the NA and EU servers, and when I go to access these 'account wide purchases that are for use by ALL characters on my account' I have found them to not be available on both servers.
Why?
I can understand things that are character specific, but account wide use.. is not available to my entire account as advertised.

However, all items purchased via the Crown Store are only available on the server where they were purchased. For example, if you buy a pet on the North American megaserver, it will only be available when playing on the North American megaserver. If you want the pet to be available when playing on the European megaserver, you will need to purchase that pet on the European server.
