You seem to be implying that this is not a good use of their resources. Note that $1500 is approximately 1 week of developer time. If they have any interest in developing RVM for their own use, this seems like a good investment. It also directly buys them a year of advertising with their name on the RVM website, which may well attract people who are currently looking for hosting solutions. Given these potential benefits, you need to explain what would be a better use of $1500 for them.
Furthermore, your comment also seems to be implying that DigitalOcean is showing a pattern of wasteful spending (the 'more' part of the "There goes more"). I hadn't heard of any indication of this, can you cite examples of this happening?
By adding these components to your comment, although I might disagree with your analysis, you've at least staked out a position, and provided information, thus contributing to useful conversation (or at least an informative read). Without them, unfortunately, your comment is mostly mean-spirited silliness. Of course spending money results in VC money being spent. This isn't necessarily a bad thing; It's the whole point! You need to explain why this isn't a good use of money.
Your post is a fantastic breakdown on why such comments are unhelpful and shortsighted and in a very helpful tone.
Keep up the good work!
