If you block only spammers you'd be right. But SendGrid is one of the sorry cases where you have spam and legit, sometimes important e-mails coming from the same network. Your users won't be happy if you reject their order confirmations or online tickets.
Blocking sendgrid would also lop off a large number of small self-hosted mail instances that use sendgrid for reasonable deliverability. Which boils down to actively punishing de-centralised mail.
