I got rid of tips by deleting them in tips and info app and stopped them syncing.

I did try that that before. In fact I tried to delete the entire app (which can't be done - at least I couldn't). I presume that for some that may be part of the solution but that alone didn't not work for me as mine stubbornly did not move.
I called HTC about the matter and now although the 2 remaining tiles are still present, they have been relegated to the bottom of the blinkfeed so it's not much of an issue anymore. Hopefully they will eventually slip of the edge and be gone forever with further refreshes in the feed content - maybe. Below is an extract of the email response from HTC.

Thank you for contacting HTC regarding your HTC One.
As discussed on the phone I would like to get back to you regarding the Blinkfeed and Zoe issue on your handset.
We just tested a HTC One here and at first could not update the Blinkfeed either. Then we restored it to factory settings and after that we could update Blinkfeed again.
When you can update Blinkfeed you will see that if you add interest to Blinkfeed the tile 'get the latest news that matters to you' will be moved further down, and will no longer be visable on the homescreen (unless you scroll down).
