To each their own and it's not mine to say what's right and wrong. Having said that, I went and reviewed (briefly) Samsung's T&Cs here (https://account.samsung.com/membersh...amLocale=en_GB) and the closest thing I found was this:

8.3. Samsung does not claim ownership of the User Content and You will retain any copyright and any other rights to any User Content provided by You on or through the Services.
Then I went here: Mobile Nations - Terms And Conditions and found this:
You may submit comments and provide other content so long as the content is not obscene, illegal, threatening, or defamatory and so long as the content does not invade the privacy or infringe the intellectual property of a third party. Further, such content may not contain software viruses, mass mailings, chain letters, or any form of "spam." You may not use a false e-mail address, impersonate any person or entity, or otherwise mislead as to the origin of the information.
By submitting information, you grant Mobile Nations a nonexclusive, royalty-free, perpetual, irrevocable, and fully sublicensable right to reproduce, use, modify, publish, adapt, translate, create derivative works from, distribute, and display such content throughout the world in any media. By submitting information you also represent and warrant that that the content is accurate; you own or have permission to use the content that you submit; and that use of the content will not cause injury to any person or entity.
Mobile Nations reserves the right to edit or delete any comments, at any time, as deemed necessary due to member conduct without warning.
The latter is from the website that you are currently on. Granted, you may be more concerned about people in South Korea paying attention to what you watch, but I think the point is that all of your data is out there and if you think HTC is less intrusive (or any other company), I think you may be pulling your own leg.
I keep myself private by leading a wholly uninteresting life that no one cares about but YMMV! :D
