Before you have product-market fit... vendor lock-in doesn't matter. The only thing that matters is getting to product-market fit. If you have some product-market fit, vendor lock-in probably doesn't matter. If your business is growing quickly and you have the ability to raise a strong Series A investment (if you wanted to), then vendor relationships are worth thinking about and engineering for the long term. Giants like Amazon, Facebook, and Google don't want to "control your stuff before you even make it" because most things that people make aren't worth their time. Once your business is growing steadily, however, this might change.
