What's the best alternative? Flickr?

I don't want to self-host my photos, too much management.

I don't want to use Apple or Google or MS Clouds for various reasons.

I do want to support a pure-play, independent-ish, profitable, consumer friendly platform. To upload hires shots and have them easy to tag/share/access among those to whom they may be of interest.

I expect to pay, but not through the nose. Reliability matters. I would want the company to be around in 20 years and still reasonably priced/useful. Suggestions?
