Pros
The acquisition by Qlik (or anyone else) was long overdue and may stop the demise of Talend.
Cons
Talend offers an ageing, outdated technology platform that has not seen a lot of innovation in the last five years. The key components are clobbered together to form an 'integrated platform', that only exists in marketing brochures. Major cloud providers, Databricks, Snowflake, DBT and a few niche players drive the real innovations in the data industry. Talend is still trying to understand what the cloud is about. Studio, REs, TDC & TCDC are all on-prem components (or IaaS of course). The Qlik acquisition may slow down the decay of the Talend platform - IF they invest in rearchitecting the current mess. It won't be cheap, but without it Talend is dead as a herring.
