Unfortunately “legit” companies do the same.
Vagueness: ✓. While often pointing to specific URLs or documents, it’s 20 pages of dense legalese and you need to find for yourself, what they’re referring to.
Sketchy domains and link shorteners: ✓. Not only from some small companies, but major players. Like sending an SMS with “click this” shortened URL, or mass mails from spam-company-14ufnb24.com. Most companies also lack their own domain, but use whichever “free” email provider is popular in a given country: company-name-1461(at)gmail.com is pretty normal.
The urgency: ✓. “your bill is due in 3 days, click this link,” unclear “we enabled a service on your phone” with a link to details, or “there is a problem with your shipping.”
There is a pretense of high security and teaching good practices, followed by completely ignoring all this and doing what’s easier and cheaper.
