That's an incredibly broad statement; we are talking about what movies people have watched on netflix. What possible non-anonymous dataset could you be cross referencing to de-anonymize it? Even if you could, who cares?
perl -Mstrict -WE 'my $test; say @{ $test };'
Can't use an undefined value as an ARRAY reference at -e line 1.
What harm is there in a warning? You can disable classes of warnings in perl if you want to, or turn them off completely. I would much rather be explicit so I don't accidentally use some magic. perl -wE 'my @test; say $test[5]{yes}[0]{ok}++; say scalar @test; say ref $test[5]; say $test[5]{yes}[0]{ok}'
outputs: 0

with not a single warning IBM does not have a technical answer to OpenLava and to the benefit its users have.
They cannot articulate why their software is better than OpenLava for the money they charge for it.
IBM fears OpenLava because is does provide a better functionality than their own software and
that's why it can only reply with a lawsuit by hiring:
Kirkland & Ellis LLP.
Sounds like there might be slightly more to this than is outlined in comments.
