Regarding this proposal and how it goes, I would like to remind you all here some past threads from the seller of bitshares.com
You can see them here back in 2014
https://bitsharestalk.org/index.php/topic,3819.msg58711.html#msg587114 BTC back then was $2500 and a couple of weeks ago that 4BTC were worthing $80,000. Back then the seller said that if someone would offer $100,000 he would take the offer. Obviously the $100,000 back then was by far exceeding his expectations for a domain name so I would assume that he would accept $30-$50k back then. Moreover most of the community members were just fine with .org back then and did not want to buy the .com
In addition in May 2016 (2 years later) the seller was saying that the domain will be soon sold. I guess it never did..
https://bitsharestalk.org/index.php/topic,22662.msg294650.html#msg294650Now again this topic is raised 2 years afterwards...So I see that every 2 years we are discussing this.
Anyway...My take on all this is that since as a community back then we did not care about .com (we could have bought is for $30k - $50k), we were happy about .org, we never created a similar worker proposal in 2016, I am on the opinion that the offer from the worker proposal should not be more than $80,000 and the seller since he claimed was also a bitshares shareholder he should be more than happy with this offer.
This is only my opinion, obviously the beauty of bitshares system and voting will define the right course of action
