I love the spin job from the spokesman Matthieu Rozen:
"Our organization does not sponsor any proselytizing campaigns in funeral homes.If an individual is moved by love and faith to share their condolences and the Bible's comforting words with a person in grief, that is a personal choice."
Of course you do not encourage preaching in funeral homes - that would border on illegal and be highly inappropriate, even by JW standards.
However, you have encouraged people to contact grieving families in cemeteries and through reading obituaries - as noted above. We used to have an elder who would go to cemeteries all the time - I refused to participate nor would I ever recommend it. I thought it was highly inappropriate.
The lady in the video handled it very classy - she was direct and had a right to be angry. You can offer your condolences without any reference to the bible or JW.org if you care that much. The sad part is you know these people were doing this all in the effort to get service time. Probably some poor pioneer slogging away to get some hours. I am sure that is what Jesus and Paul were talking about in the scriptures.
