As they require EBS backed volumes. It's something of a technical limitation... So under the Hobby plan Small is the smallest server you can have. If you are just 'playing around you could team it with TKLBAM and backup your data and turn it off when you aren't using it and relaunch it with your backed up data...
Also, another option is to do the free budget 14 day trial and refer some friends. If one of them signs up (AFAIK no purchase is required, just sign up to the Hub with a valid AWS account) then you can have free (excluding AWS charges) micro servers!
