I could be wrong on this, but I would think the wheels would come fully assembled and ready to go from the manufacturer, and the bike shop had nothing to do with installing the rim tape. Basically you didn't double check with the bike shop/anyone who might have the appropriate information as to whether the rim tape was tubeless ready. You set up your wheels, made a big mess with sealant, and looked to blame someone for your own shortcomings. When I bought my first bike with tubeless ready wheels, I asked my shop what I needed to do/buy to run them tubeless. Then I purchased said items and never had any issues.
Yes, the bike shop has nothing to do with installing the rim tape. However, if the rim tape was defective they would still be responsible for fixing it as the retailer, which I thought was the case. And if you read my original post, I didn't even blame them, I simply asked if my train of thought (based on the assumption that the tape on it was tubeless tape) was correct. So I don't know where your criticism is coming from.
And again if you read my posts, my whole point is that it's not
my 'shortcomings' that so-called tubeless ready wheels are not ready for tubeless. There's an issue with standardisation of these terms which is causing confusion to lots of people. Why would that be my shortcomings?
Also clearly it's in our (cyclists', consumers') interest to promote the provision of tubeless tape with tubeless ready wheels as many brands are already doing. So I'm not quite getting the intentions of those who want to blame consumers for thinking that tubeless ready wheels would be ready for tubeless.
