Very interesting to see the current poll results...
Is the Bitcoin protocol's privacy "good enough"?
Yes - 17 (35.4%)
No - 14 (29.2%)
Not yet, but it will be after the taproot upgrade - 17 (35.4%)
Total Voters: 48
To me, if we ignore the Taproot upgrade for a moment and combine 2 and 3 the results would be something like this
Is the Bitcoin protocol's privacy "good enough"?
Yes - 17 (35.4%)
No - 31 (64.6%) <------- 65% says No
Total Voters: 48
What does it mean? Aren't we satisfied with Bitcoin's protocol privacy?
Don't confuse privacy with security. As far as security is concerned, I think it's rock-solid, as has been shown by more than a decade of failed attacks and attempts to break it. No issues there.
As far as
privacy is concerned, things are not so good -- yet. There are ways to protect it, but it's not automatic, one has to be aware of the various privacy issues and do things in certain ways in order to protect it. I think this is what's reflected in the poll result.
