Hey Google, my friend was just in an accident, she now has lost her eyesight, needs reconstructive surgery, will never walk again, and has severe brain damage, could you not try to sell me insurance right at this moment? Could you maybe consider that to be just a bit insensitive. Yes I understand you need to make a profit, but it would just be nice if you didn't go through my emails and advertise based on the most morbid of it all.
You should take it with a grain of salt. If it would be possible not to see those ads, it might still be you put on the television and there is an advertisement about something like that. Just ignore them and hopefully all will be fine for your friend.
His friend got hurt in an accident and now he is seeing advertisements of insurances and it hurts him to see those advertisements, now after the accident
I think I have been using gmail for more than 4 years now and I have never ever in my entire time ever clicked any of the ads on there. I am using 40% of my quota which is about 3Gb. I wonder if google has any benefit of providing me this service for free. I don't remember if I ever bought anything from them. I don't even click ads on youtube. I am just curious does google make any profit from these services. I think just like the OP most people are not interested in ads shown in gmail.
