This is yet another negative article with LiberOffice/TDF at the centre of it (this time with Collabora freely dragging themselves into the muck). This after attacks on OnlyOffice and OpenOffice for, from a relatively external perspective, "existing as competition".
I appreciate that for those "in the trenches" this may be a rallying cry or a shot across the bow, but for the rest of us it is indicating that we keep the whole thing - LibreOffice and Collabora - at arms length. Which is a shame because I've recommended both to people in the past, as well as happily using both at various points myself.
On the contrary, I would take this as evidence that these projects are alive and well - they have people who care enough to try to affect their future trajectory.
