Maybe ask yourself how do visitors to mail.dema.bike know what site they are on and what the site is ? Mozilla Firefox uses information and reports that Google produce. Users will be able to disregard the warning and use the site if they wish. Possibly the problem is that the page I see presents information about Microsoft & Outlook, but I see no information actually showing which site I am using or what the site is. I do NOT understand or need to understand the requirements for you to acknowledge use of Microsoft trademarks etc. but possibly the lack of information about your site is enough for Google to consider that it is deceptive site. Perhaps you need to consider what information your site should display, but that is something to take up with Google and not this forum or Mozilla.
