You are not understanding the gravity of this.
Send what I am writing in this post to the CEO of your company, I will be contacting that person this week as well. There is a very high likelihood that I will be suing you for hundreds if not billions of dollars. The potential damages of this are beyond what I can see you can comprehend.
I will give you a very real example of how serious what you are doing is. In your little message there (highlighted in red) you are implying my domain can be scamming people or doing something illegal. You are instructing me to change settings in my own machine, this means potentially tens or even hundreds of thousands of people using your software and looking at this would have to change on their own some settings so they do not see something that implies my business is either doing something illegal or can do something damaging to their devices.
Imagine for a second I run a campaign and I did not catch this on time (this malwarebytes flaw). Imagine I spend initially $1 million dollars in advertising then $20 million dollars months later. From the potential users I am targeting in my campaign let's say initially 1,000,000 of them use your system (you have about 35 million users), my average income per user for that specific ad would be $493 and the average conversion rate would be 0.005% (1 in 500 visitors buys). So that is in the first ad 2000 transactions and $986,000 in income you have made me lose directly. And the bigger problem comes from the residual, I partner with over 3,000 firms and offer over 40,000 brands, this means a new customer can do many transactions per year, generating to my business many thousands of dollars and now, due to your message I lost that customer, but it gets worse, not only have I lost the customer but that customer believes I am doing something illegal or I can damage their computer. And all why? because I have an ".online" domain.
Just how stupid are you people?
Can you grasp how serious this is? This is not a game, you are causing huge damages to my business.
Don't tell me how to go fis this in MY computer, don't tell me to give you a domain and you "whitelist" it, go fix this issue immediately, you cannot blanket block domains due to their domain extension, that is so idiotic and in my case it has exposed you to a lawsuit in the billions of dollars you idiots.
Saying I am furious about this could not even begin to describe how I feel.
