And that is enabled by VC funded culture, where you have million of dollars invested in companies, which can then offer services at a loss investing in something else (market share, training data, etc.).
Using smaller companies which charge honestly for the services they provide is probably more sustainable in the long term.
(I use Flickr, Gphotos and an S3 bucket but I’m paranoid)
Also, Flickr has done an arguably nastier bait and switch when they announced the end of their unlimited free storage. At least Google seems to be willing to keep the photos already uploaded around. For now.
Smaller companies also commonly get acquired, shuttered, or become big companies in their own right. There's no panacea here. I think by the third or fourth time I was migrating from "the honesty priced option" the reality settled in that "honestly priced" is usually just an uninventive advertising moniker used for overpriced underdeveloped products.
