To send promotional email and potentially sell your address, first and foremost. I recently subscribed to a trial of a large VPN service and receive almost daily advertising mail. “Account management” might be one point as well, but is certainly secondary and most likely often used as an excuse.
Easy one is most users forget their passwords.
On average on a large platform, we see about 15% of users a day tap that button.

Maybe you’re on some kind of trial mailing list? I checked my TG emails and there isn’t a single ad/promo email. Everything is invoice/account related.
Because that kind of activity doesn’t sound like what a “large VPN service” would need/want to do.
You should always have a “fake” email address for sign ups and such IMO. This way your main account doesn’t get bogged down.
that is what disposable email is for. but in fact i would not do business with a company selling info. with disposables (sneakemail still exist?) you can aksobtrack, who gives emails away.
Also, possibly to market future security products to you. Further, all services require some kind of user account (even if you don’t have a traditional profile), thus the email address ask.
as someone who works in this field for a company that does not ask for an email… users really forget their details quite often and I really wished we had asked for an email for the easy recovery option 
Email address can be optional - it is on Reddit.

Of course they don’t harass customers with an active subscription.

“Disposable email” domains are universally blocked from registration. Google, Microsoft, Yahoo and mail.com may ask or require a verified phone number.
I’ve tried 3 different VPNs the last 3 months. The ones I no longer have an active subscription to, I haven’t received one thing from them after the “Please try us one more time” email.

Yandex Mail doesn’t need any phone number, and there are a billion others.
can be blocked as well, not a common provider
I wasn’t able to create an account when registering from my own IP address, and not from VPN either. There was no way to proceed: https://i.imgur.com/WWAbvEl.png
Google can require a phone number.

Sexual slurs on on the website, one of the domains is “hitler.rocks”.
You’re just picking straws, I’ve never had a problem signing up with my personal email server. I’ve only ever seen maybe one or two services (neither vpn related) that required you to use a ‘common’ email provider, and they promptly lost my business because that’s a superbly dumb practice.

If you can, try and VPN to Finland. I’ve created couple gmails that used other email as verification. No phone# needed.
You have a bone to pick don’t you?
It’s what 99% of accounts require because if a customer can’t get into a service, then the customer won’t pay for said service.
Then there’s also a check box two thirds of the time that says “sign up to newsletter”
If they send promo mail…filter it out
