Most incisive were his criticisms of some confused socio-economic analyses (including the exaggerated estimate of the level of urbanization and industrial development already reached in the country, as against the continuing and even worsening pre-industrial and semifeudal socio-economic state of the country) and, more importantly, his criticisms of some revisionist errors in revolutionary tactics prevailing then, including the premature “Strategic Counter-Offensive” and “Regularization of the New People’s Army”, given that the people’s war was then still at the early sub-stage of the strategic defensive. After his release from prison and initial peace talks were held between the NDFP and the Cory Aquino government, he criticized the NDFP's handling then of the peace talks and wrote about how it should instead be handled.
Ang pinakamatalas ay ang kanyang kritisismo sa ilang tulirong sosyo-ekonomikong pagsusuri (kabilang ang eksaheradong pagtaya sa antas ng urbanisasyon at industriyal na pag-unlad na narating na ng bansa, kontra sa nagpapatuloy at lumalala pa ngang pre-industriyal at malapyudal na kalagayang sosyo-ekonomiko ng bansa), at ang mas mahalaga, ang kritisismo niya sa ilang rebisyunistang kamalian sa umiiral na rebolusyonaryong taktika noon, kabilang ang adelantadong “Strategic Counter-Offensive” at ang "Regularisasyon ng Bagong Hukbong Bayan," na kung tutuusin ay nasa maaagang subyugto pa lamang ng estratehikong depensiba ang digmang bayan noong panahong iyon. Pagkalaya niya mula sa piitan at sa panimulang usapang pangkapayapaan sa pagitan ng NDFP at ng gubyernong Cory Aquino, pinuna niya ang paghawak ng NDFP sa usapang pangkapayapaan noon at nagsulat siya hinggil sa kung paano ito dadalhin.
