If it matters at all to you, you can host a huge amount for static website content for single digit dollars per year on S3.
If it's not worth that much to you, who in their right mind will build a service based on providing that to you at your price point? And if they _have_ a service where the marginal cost of you not-caring-enough-to-pay makes little difference, you should - as this Dropbox change demonstrates - fully expect that "feature" to go away when the costs or support (or legal problems) get noticed.
Unfortunately, I don't think that "if it matters so much to you, you can pay $X" is a useful position. More helpful would be "beware free services that cause vendor lock-in and may stop being free at any time".
