这张截图来自明讯创始人的朋友圈，我最开始于 3 月 20 日发布在我的公众号里。 关于初创公司 - 明讯科技，和投资机构 - 同创 wy 的纠纷，不知还有多少人不了解背景。 我当时发布的文章，除了这张截图外，还有来自鲸准 app 的，同创投资明讯的截图。除此之外，没有我的原创内容。 然后， 20 日下午，同创发出一则公告，称明讯创始人的指控严重不实，同时也要求各自媒体删除相关内容。 同时，创始人也删除了朋友圈的内容。于是，我也删了我的文章。 有小伙伴问我删掉的那篇是什么内容，为什么删掉，我在此做个补充解释。 关于这份纠纷，公众号"创投日报"于 3 月 22 日发布了对明讯创始人的专访，比较真实全面的还原了事件过程。 我在 3 月 31 日发布的《回购的真实模样》，也部分是在为这件事，为创始人发声。 在我眼里，大部分创始人在投资机构面前是相对弱势的一方，是信息不对称的一方， 而且，我曾按合伙人的指示，亲手在回购和落地等事项上，让初创企业元气大伤，让企业新一轮难以为继。 我的价值观让我不得不为创始人发声。如果我有偏颇，有说的不对的地方，我承认。我毕竟只是一个个人公众号。 然后，在《回购的真实模样》的评论里我有提到 ...
