AWS has their own competitive service against DigitalOcean called Lightsail. Their cheapest plan is $3.50 month (512MB/20GB SSD), the bigger plans are roughly similar in pricing and features to DigitalOcean.
Do yourself a favour and compare the performance of DO and Lightsail before you migrate. It may be the same or similar in pricing, but every benchmark I've seen shows worse performance on Lightsail. On a value for money basis, Lightsail is most likely more expensive.
Why migrate? Afaict, Digital Ocean isn't going anywhere, it's mostly internal restructuring. I'm sure you posted before the comment by one of the cofounders, so definitely give it a read before you make any decisions.
Personally, I have more instances on vultr and linode, but I still keep an instance at DO so I have a reason to keep tabs on them. I have no qualms about recommending their service to others.
