Own it, rather than renting it

I have conceived this idea a while ago, but today I am further inspired by once.com, that 37signals mentions the same idea - that you should
you owned what you paid for, you controlled what you depended on, and your privacy and security were your own business.
Here’s a draft of my idea when I thought about it, and I will develop it into a full article when I have time. Take Back Control When You Need To Self Hosting
Your data should belong to you
Many services claim that you have 100% control of your data, but they can change their terms and promise at any time. Even if it's not changed, how "100%" can you control it? What if the service is down, bankrupt, what if they require you to submit a request form, what if ... I used to use raindrop.io for bookmarks - it’s near to perfect. The only thing is that it’s close-sourced and everything is hosted by the website. I have no say in how, where, when I can access my data. I then turned to Shiori, an open-source, self-hosted alternatives. I love it, and it also provides full-text read-mode and snapshot, which means you can still access the content of the bookmarks even when the actual websites are gone. Self-hosting such a different experience. Self Owned
Sometimes, only owning it at your hand is safe
Further, what if hosting service is down or becomes hostile to you? What if you need to "waive... agree with ..." to just use it? What if you need it INSTANTLY without being queued? What if you don't wanna being limited by network? Software-as-a-Service is when you give all your trust to a company or person that they are gonna abide the rules they set, while there’s zero you can do when they don’t. Remember: almost all terms of service have the almighty sentence that “the terms of service is subject to changes without notice and we reserve the right of interpretation…”. You could certainly go with it when the convenience exceeds the risk, but don’t otherwise.
