As far as what was actually said at the convention is concerned, the outlines are available to read for yourself.
This is the outline for the talk titled 'Shun Unrepentant Wrongdoers'

The outline says the following
Loyal Christians would not associate with “anyone called a brother”
who is practicing serious sin. This is true even if no congregation action has been taken, as may be
the case with an inactive one (w85 7/15 19 14)
This can be a real trial when a family member is involved. We must not allow strong family ties to lead us to compromise loyalty
to Jehovah and his organization (w13 1/15 15-16 16-20)
They use the term 'serious sin'. That to me does not mean someone who is merely not going to meetings. But I suppose jws will often go beyond the things written as it were.
There was a talk given on Saturday morning regarding how to treat inactive ones.
This is the link to the outline:

It says:
THEY ARE RELATED TO US IN THE FAITH (1 min.)
We are especially interested in helping inactive ones because they are
our spiritual brothers and sisters [Read Galatians 6:10]
Unlike unbelievers, inactive ones started running in the race for
life but may have stopped because of anxieties, hurt feelings, or a
sense of guilt (Heb 12:1)
We should reflect Jehovah’s interest in helping them (Eze 34:16a)
The organization made a concerted effort to visit inactive publishers
during the recent Memorial season, and our interest in helping them
to return is ongoing
HELP THEM RETURN “TO THE SHEPHERD” (5 min.)
Inactive ones can return to Jehovah [Read 1 Peter 2:25]
Jehovah sent prophets and finally his Son to help the nation of
Israel to return (it-2 565 3)
Jehovah can use us to help inactive ones return to him. A brief telephone call or a visit will remind them that they have not
been forgotten by their spiritual family (km 2/07 8)
When inactive publishers attend a congregation meeting, we should
welcome them warmly. Avoid asking questions or making statements that may embarrass them. When we meet inactive ones, we should promptly let the elders know. Elders take the lead in ‘going after the lost one’ (Lu 15:4-7)
They arrange to visit inactive ones at least once a year. Lost sheep are to be carried back gently by the elders (Lu 15:5)
Elders understand that sheep separated from the congregation are
likely to be exhausted from mistreatment in Satan’s world and
from lack of spiritual nutrition
Elders should ensure that all inactive ones receive a copy of the
brochure Return to Jehovah
None of that help for inactive ones involves socializing with them, but they do not mention this applying to family in this talk, so it seems to me like they are not counseling against socialising with a family member who is inactive but not carrying on serious sin.
Personally, I faded quite some years ago, and I haven't yet had any witness family change their behaviour toward me in the last six months. If they became aware that I was doing something deemed 'serious sin' I suppose that would change. Everyone's experience will be different though, because it relies on individual jw consciences.
