Most startups choose AWS for their hosting, where they're paying a ~10x premium over dedicated boxes. Budget obviously isn't the deciding factor even for cash-strapped new tech companies, not when we're talking about just 100EUR.
Cash-strapped startups are not choosing DigitalOcean, they're choosing AWS. That's their point of comparison. Your assertion was that 100EUR would be a barrier to startups, not just to yourself.
Off-topic but do you get mistaken for the lecturer Dan Grossman? Especially around here since he did a coursera functional programming course earlier this year?
