The reason people do it is because they got burned in the past with websites that started spamming them/were not as advertised.
Rate-Limit accounts from disposable emails if you must, but if you see activity past the duration of the disposable email, offer these accounts a way to transfer over to a permanent email.
As the (previous) operator of a reasonably sized community forum: A prominent user of disposable emails is griefers and trolls who use it for ban evasion.
Preventing disposable email registration pushes the bar just that little bit higher that it really helps with these kinds of users.
In fact, this is the reason we even had email verification at all (it used to be effective against spammers, but those days seem to have gone)
Suppose you are an owner of a trustful online community you built for years. Would you like people to use one time emails on registration so you will be never able to reach them out? Disposable domains (most) are public so how about password reset, updating profiles etc.. There should be a certain level of trust between website admins and users.
P.S. And yeah, I do recommend you to check the website for trustfulness. This list is intended for good guys who respect people rights of privacy.

I'm familiar with at least two of the services on your block-list - because I actively use them. Neither of them is limited to "one time emails". One provides addresses that forward until you disable them, and the other allows a specified number of e-mails, with the option to either renew a sender's e-mail quota or set them as "trusted" (allowing unlimited e-mails). I only disable these disposable addresses as a last resort - if I start receiving a high volume of e-mails that I did not agree to receive and can't unsubscribe, or if I see that the address has been shared with a third party without my permission. If you treat me with respect, you'll be able to contact me for as long as I use your site. If you violate my trust, you'll be treated as a spammer.
Your optimizing for the wrong things. All your doing is limiting hood people with a reason to use a service and encouraging bad people to just try a different one until it works.
This is The same argument against DRM. It hurts the legit folks and didn’t impact the pirates.
