No this is untrue, We were interested in T2/T3/T4, what was listed was the flowers we didnt need. The best ones we kept and the rest we sold to the open market.
We only have t1 flowers on alioth as we used calibration tiles like everyone else for our ore : )
T3/T4/T5 on Jago was the same, we kept what we needed sold what we didnt. I know some orgs kept everything preventing access to those fields from the majority of players but I can confirm on Jago we sold many flowers. TRIs to players and orgs of all sizes.
We will do the same on the next planets, we arent hoarders, we just love scanning : ) its like the rush you get from scratching a scratch card : )
